W-AM-Pos5 SATURATION TRANSFER EPR SPECTROSCOPY ON SPIN-LABELED MUSCLE FIBFRS USING A LOOP-GAP RESONATOR. David D. Thomas, Christine H. Wendt, * W. Froncisz, * James S. Hyde, Dept. of Biochem., Univ. of MN, Mpls, MN, * Nat'l Biomedical ESR Center, Medical College of WI, Milwaukee, WI. Previousiy, saturation transfer ST-EPR ; studies of biomolecular d: narnics have involved the use of a resonant cavity and the V2' display absorption, second harmonic, out-of-phase ; . In the present study, we replaced the resonant cavity with a loop-gap resonator and used the U1' display dispersion, first harmonic, out-of-phase ; to study spin-labeled muscle fibers. The new resonator produced virtually noiseless U1' spectra on a 0.4 pl sample using a 4 minute scan; whereas previous U1' experiments using a conventional rectangular cavity resulted in an unacceptably low signal-tonoise ratio. The high filling factor of the new resonator facilitated the study of these extremely small fiber bundles and permitted high microwave field intensities to be achieved at much lower incident microwave power levels, thus greatly enhancing the signal-to-noise ratio. This made it possible to benefit from the other advantages of U1' over V ', such as stronger signals, simpler lineshapes, and simpler data analysis. For these muscle fiber samples, the resulting sensitivity signal noise sample volume ; of the U1' signals was more than 100 times that of V2' signals obtained in a conventional cavity. Another advantage of the U1' display is that signals from weakly immobilized probes nsec motion relative to the labeled protein ; are greatly suppressed relative to strongly immobilized probes. This reduces the ambiguity of spectral analysis, and eliminates the need for chemical treatments e.g. using K3Fe CN ; 6 ; that were previously required in muscle fibers and other systems. Further suppression was achieved by increasing the microwave power and decreasing the field modulation frequency and guanfacine.

Derived from S. lividans can catalyze the 4'phosphopantetheinylation of BPSA from S. lavendulae. In fact, several Streptomyces strains possess a PPTase that displays high similarity to Svp 15 ; . Chemical Structure of the Blue Pigment from S. lavendulaeWe found that S. lavendulae ATCC11924 produces inductively the blue pigment by the addition of -nonalactone our unpublished data ; . The Streptomyces blue pigment was analyzed by IR, MS, and NMR spectrometry in order to determine the chemical structure. The IR spectrum of the blue pigment represented the existence of a double-bond of carbon, associated amine groups, and amide. The absorption maximum of the blue pigment in various organic solvents is summarized in Table 2. These values were very similar to those of 5, 5'diamino-4, 4'-dihydroxy-3, ; , called indigoidine, as shown in Fig. 3A 9, 10 ; . MALDI-TOF and EIMS analyses yielded a peak at 248.0 m z Fig. 3B ; , interpreted as a radical positive ion, which corresponds to the theoretical molecular weight of indigoidine. The 1H-NMR spectrum of the blue pigment gave three peaks Fig. 3C ; . The signals at 8.18 ppm, 6.46 ppm, and 11.30 ppm correspond to the protons of -C CH-, -NH2, and -CONH-, respectively, which can account for the structure of indigoidine. Although 13C-NMR analysis was hampered by the poor solubility of the pigment, we concluded that the chemical structure of the Streptomyces blue pigment is identical to that of indigoidine. In Vitro Analysis of the Purified BPSASince BPSA is an NRPS of a single module-type, the blue pigment must be synthesized from only one amino acid. In an NRPS module, amino acid recognition and activation occur by reacting with ATP bound to the A-domain. The site, which specifies an amino acid as a substrate, is located between motifs A4 and A5 in the A-domain 22, 23 ; . The crystallographic analysis of the Adomain in gramicidin S synthetase GrsA ; in complex with L-Phe 24 ; revealed that eight amino acids, located between the A4 and A5 motifs, are responsible for the recognition of the amino acid utilized as a substrate. The relationship between the corresponding eight amino acids and the substrates has been investigated about many.
The lamellar lattice constants d of the DMPCGD samples studied show that incorporation of GD leads to an extraordinary large d-spacing in the gel phases. This swelling might be induced by the formation of longer, double helical forms of gramicidin in long-chain gel-type lipid bilayers or by the swelling of the interlamellar water. The former mechanism can probably be ruled out by recent FT-IR spectroscopic data 17 ; , which showed that, in contrast to long-chain phospholipids - gramicidin mixtures with lesser hydrophobic coupling, the helical dimer structure of GD is prevailing in both, fluid and gel phases of DMPC 18 ; . To explore the effect of pressure on the structure and phase behavior of the DMPC polypeptide mixtures, we studied the pressure dependence of the SAXS diffraction patterns of DMPC and the DMPCGD mixtures at temperatures of 21 and 37 C. In pure DMPC dispersions at 37 oC Fig. 4 ; , a shift to lower scattering vectors together with a change in the lineshape is observed at ~500 bar, which is due to the pressureinduced L to P' phase transition; the corresponding lamellar lattice constant increases from 62 to ~65 Fig. 5 ; . Further increase in pressure results in a decrease of the dspacing and a further pressure-induced gel-to-gel phase transition around 2000 bar, leading to a decrease of the lamellar repeat period to d 57 , which is almost insensitive to further pressure increase Fig. 3b ; . The high pressure SAXS data of the DMPC-2.2 mol% GD mixture at 37 oC are depicted in Fig. 4b. The fluid phase is observed up to ~500 bar, where the fluid-to-gel transition occurs Figs. 3b, 4b ; . A ripple gel phase is not found anymore, even at this low peptide concentration. The pressure dependence of the d-spacing has a different sign compared to the pure DMPC bilayer. It increases with increasing pressure, from 68.3 to 73.3 at 2200 bar. At higher pressures, a two-phase region is induced, probably a GD-rich Gel' ; and a GD-poor Gel'' ; lipid gel phase, which might be due to the increasingly hydrophobic mismatch between the lengths of the lipid chains and the polypeptide upon pressurization. The corresponding lattice constants of the Gel' and Gel'' phases are 71 and 60 , respectively, and are insensitive to further pressurization of the system. A similar scenario holds for the DMPC-4.4 mol% GD mixture. The highpressure gel-gel phase transition occurs around 2600 bar for this system. The data thus clearly show that incorporation of gramicidin drastically changes the pressure dependent gel phase behavior of DMPC. Further SAXS data were taken at 21 oC, i.e., starting in the P' gel phase of the lipid bilayer system data not shown ; . At ambient pressure, the d-spacing is 66 at 21 pure DMPC, decreases upon pressurization, and at p 2400 bar the transition to the L' phase occurs d 59.5 ; . Up to 3800 bar, the d-spacing decreases only slightly ~1 ; and no indication of a further pressure-induced gel-to-gel phase transition occurs. Addition of e.g. 2.2 mol% GD leads to a drastic swelling of the dspacing up to 70.5 at ambient pressure. The d-value increases slightly with increasing pressure, and a two-phase region is detected at ~800 bar, which extends up to the full pressure-range covered. The corresponding d-spacings differ of the two gel phases by ~13 . The smaller one with d 60 is similar to that of pure DMPC, suggesting that the increase in d-spacing in the second gel phase domains with d 73 is due to the insertion of GD. This increase in d-spacing is largely due to the increase of the interlamellar water layer vide infra ; , which is probably caused by an increase of undulations of the opposing lipid bilayers induced by the GD insertion, leading to a and guarana.
Function of gramicidin a
Because gramicidin exhibits these characteristic channel states only in true bilayer membranes, their visulisation provides additional evidence that the pipette is sealed by a single lipid bilayer and gramicidin.
That water moves rapidly over the uncharged polar surfaces that make up the inner walls of the gramicidin channel. This result is consistent with recent NMR measurements of the rate of water movement on the surface of lysozyme Bryant and Shirley, 1980 and halcion.
Binding site after binding of QUI molecule. This conformational change would allow FEL easier access to the active oxygen and results in increased catalytic activity 2-fold increase in the Vmax ; . Various two-site kinetic models were applied for further analysis of the contrasting effects of HAL and QUI on FEL CYP3A4-mediated metabolism. The kinetic parameter estimates for HAL, generated from a fit to eq. 2, are presented in Table 3. Potent inhibition Ki 3.4 M ; can be rationalized by the favorable formation of a complex containing both the substrate and modifier, as changes in are not pronounced. Estimates of the parameters generated from the fit to eq. 2 for the effects of QUI are shown in Table 4.

ABSTRACr Normal mode frequencies have been calculated for single-stranded j344 and O3 and for double-stranded t 4 1-566 t1#7.2, t1T5 6, and t1t7-2 helices that are possible models for the structure of gramicidin A. The force field used in the calculations is one that reproduces the frequencies of model polypeptide chain structures to about + 5 cm-l and is therefore expected to provide meaningful distinctions between these conformations. The calculations predict significant differences in the infrared and Raman spectra of these , B-helices, suggesting that they should be identifiable from their spectra which is shown in the following paper to be the case ; . The most sensitive region is that of the amide I frequencies, where the predicted patterns of intense infrared mode, infrared splittings, and intense Raman mode provide and granisetron.
