Mechanistic Understanding of Lanthipeptide Biosynthetic Enzymes
Lanthipeptides are ribosomally synthesized and post-translationally modified peptides (RiPPs) that display a wide variety of biological activities, from antimicrobial to antiallodynic. Lanthipeptides that display antimicrobial activity are called lantibiotics. The post-translational modification reactions of lanthipeptides include dehydration of Ser and Thr residues to dehydroalanine and dehydr...
متن کاملUnderstanding allosteric and cooperative interactions in enzymes.
The paper that introduced biochemists to the idea of allosteric feedback inhibition [Monod J, Changeux J-P & Jacob F (1963) J Mol Biol 6, 306-329] is now 50 years old, and the two papers on models for enzyme cooperativity that followed it [Monod J, Wyman J & Changeux J-P (1965) J Mol Biol 12, 88-118; Koshland DE, Némethy G & Filmer D (1966) Biochemistry 5, 365-385] are almost as old. All of the...
متن کاملCytochrome P450 enzymes: understanding the biochemical hieroglyphs [version 1; referees: 3 approved]
Cytochrome P450 (CYP) enzymes are the primary proteins of drug metabolism and steroid biosynthesis. These crucial proteins have long been known to harbor a cysteine thiolate bound to the heme iron. Recent advances in the field have illuminated the nature of reactive intermediates in the reaction cycle. Similar intermediates have been observed and characterized in novel heme-thiolate proteins of...
متن کاملElastic network models for understanding biomolecular machinery: from enzymes to supramolecular assemblies.
With advances in structure genomics, it is now recognized that knowledge of structure alone is insufficient to understand and control the mechanisms of biomolecular function. Additional information in the form of dynamics is needed. As demonstrated in a large number of studies, the machinery of proteins and their complexes can be understood to a good approximation by adopting Gaussian (or elast...
متن کاملUnderstanding Lignin-Degrading Reactions of Ligninolytic Enzymes: Binding Affinity and Interactional Profile
Previous works have demonstrated that ligninolytic enzymes mediated effective degradation of lignin wastes. The degrading ability greatly relied on the interactions of ligninolytic enzymes with lignin. Ligninolytic enzymes mainly contain laccase (Lac), lignin peroxidase (LiP) and manganese peroxidase (MnP). In the present study, the binding modes of lignin to Lac, LiP and MnP were systematicall...
