WebMar 10, 2005 · Methanobactin is an extracellular, copper-binding chromopeptide from the methane-oxidizing bacterium, Methylosinus trichosporium OB3b, believed to be involved in copper detoxification, sequestration, and uptake. Although small (1217.2 Da), methanobactin possesses a complex three-dimensional macrocyclic structure with … WebThese findings confirmed the origin of the chromopeptide as a result of intramolecular photolytic cleavage of the bond between the amino group and the αcarbon of His65 and also to tryptic...

Webchromopeptide showed a mixture of the 2187.11-Da species plus a congener having lost an additional 2 Da, with approximately equal amplitudes (Fig. 1A). Loss of 2 Da immediately suggested an additional dehydrogenation, for which the most plausible location would be within the remnants of Gln-66 to form an acylimine, as shown in structure 2 of ... WebPc. chromopeptide have been demonstrated for geometric iso-mers (E-configurated) prepared from all-Z-configurated Pr chromopeptides and phycocyanin chromopeptides (11). Similar properties also were reported for E-configurated bilindiones (12-17). It was concluded that the chromophore of the Pfr pep- optimix ag

WebAug 5, 2024 · Chromopeptides hydrolyzed from CPC could be a potential blue colorant with biological activity. • Peptide-chromophore complex is stabilized by hydrophobic interaction and hydrogen bonding. • Six plausible binding regions of chromophore with peptides are identified responsible for the chromopeptide function. Abstract WebMethanobactin (mb) is a chalkophore produced by Methylosinus trichosporiumOB3b. This chromopeptide appears to be a part of the copper acquisition system of these methane-oxidizing bacteria. We have obtained detailed NMR spectra of mb after titration with Cu(II).
