Remark 250 | REMARK: THIS STRUCTURE WAS DETERMINED BY MEANS OF 13C-ENHANCED FOURIER TRANSFORM INFRARED ...REMARK: THIS STRUCTURE WAS DETERMINED BY MEANS OF 13C-ENHANCED FOURIER TRANSFORM INFRARED SPECTROSCOPY (FTIR). DATA SET CONSISTS OF 19 CONFORMERS DERIVED FROM MOLECULAR DYNAMICS IN A MODELED SDS MICELLE SURROUNDED BY WATER WITH PEPTIDE BACKBONE CONSTRAINTS FROM FTIR. EXPERIMENTAL DETAILS EXPERIMENT TYPE : INFRARED SPECTROSCOPY TEMPERATURE (KELVIN) : 298 PH : 7.4 IONIC STRENGTH : 0.271 PRESSURE : AMBIENT SAMPLE CONTENTS : THIS STRUCTURE WAS DETERMINED USING 13-C ISOTOPE ENHANCED FTIR SPECTROSCOPY ON A FAMILY OF SELECTIVELY LABELED CHEMICALLY SYNTHESIZED PEPTIDES. 13-C CARBONYL LABELS INCLUDED RESIDUES 519,521,523,524,525,526,527, 528,529,530,531,532,533,534,538,539. EXPERIMENTS CONDUCTED : 13C-ISOTOPE ENHANCED FTIR SPECTROMETER FIELD STRENGTH : NULL SPECTROMETER MODEL : RESEARCH SERIES SPECTROMETER MANUFACTURER : MATTSON FTIR STRUCTURE DETERMINATION. SOFTWARE USED : WINFIRST FTIR CURVE FITTING SOFTWARE METHOD USED : MOLECULAR DYNAMICS CONFORMERS, NUMBER CALCULATED : 20 CONFORMERS, NUMBER SUBMITTED : 19 CONFORMERS, SELECTION CRITERIA : STRUCTURES WITH ACCEPTABLE COVALENT GEOMETRY BEST REPRESENTATIVE CONFORMER IN THIS ENSEMBLE : 1 REMARK: THE COORDINATES IN THIS ENTRY WERE GENERATED FROM 13-C INDUCED SPECTRAL SHIFTS WHICH GIVE RESIDUE-SPECIFIC SECONDARY STRUCTURE INFORMATION.
