A quantitative index of substrate promiscuity.
Catalytic promiscuity is a widespread, but poorly understood, phenomenon among enzymes with particular relevance to the evolution of new functions, drug metabolism, and in vitro biocatalyst engineering. However, there is at present no way to quantitatively measure or compare this important parameter of enzyme function. Here we define a quantitative index of promiscuity (I) that can be calculate...
متن کاملSubstrate promiscuity of N-acetylhexosamine 1-kinases.
N-Acetylhexosamine 1-kinase (NahK) catalyzes the direct addition of a phosphate from adenosine 5'-triphosphate (ATP) to the anomeric position of N-acetylhexosamine and shows similar activity towards N-acetylglucosamine (GlcNAc) and N-acetylgalactosamine (GalNAc). Herein we report the cloning, characterization, and substrate specificity studies of two NahKs from Bifidobacterium infantis ATCC1569...
متن کاملStructural basis for substrate promiscuity of dCK.
Deoxycytidine kinase (dCK) is an essential nucleoside kinase critical for the production of nucleotide precursors for DNA synthesis. This enzyme catalyzes the initial conversion of the nucleosides deoxyadenosine (dA), deoxyguanosine (dG), and deoxycytidine (dC) into their monophosphate forms, with subsequent phosphorylation to the triphosphate forms performed by additional enzymes. Several nucl...
متن کاملNRPS Substrate Promiscuity Diversifies the Xenematides
Xenematide, a cyclic depsipeptide antibiotic produced by Xenorhabdus nematophila, had a candidate nonribosomal peptide synthetase (NRPS) with atypical features. Differential metabolite analysis between a mutant and wildtype validated that this stand-alone NRPS was required for xenematide production, and further analysis led to a series of new xenematide derivatives encoded by the same NRPS. Our...
متن کاملSubstrate promiscuity in DNA methyltransferase M.PvuII. A mechanistic insight.
M.PvuII is a DNA methyltransferase from the bacterium Proteus vulgaris that catalyzes methylation of cytosine at the N4 position. This enzyme also displays promiscuous activity catalyzing methylation of adenine at the N6 position. In this work we use QM/MM methods to investigate the reaction mechanism of this promiscuous activity. We found that N6 methylation in M.PvuII takes place by means of ...
