WebNov 1, 2000 · Sequence analysis of this fragment revealed that it is closely related to a family of ATP-dependent enzymes that also includes dethiobiotin synthetase and the synthetase domains of two amidotransferases involved in cobalamin biosynthesis, cobyrinic acid a,c-diamide synthase (CobB) and cobyric acid synthase (CobQ). WebDethiobiotin synthetase, DTBS, (PDB id = 1a82) plays an important role in the biotin synthetic pathway. Better known as vitamin H, all organisms require biotin. Biotin’s necessity for life lies in its identity as a prosthetic group for the enzymes that catalyze the many biological carboxylation and transcarboxylation reactions (1).
WebMar 31, 1998 · The ATP-dependent enzyme dethiobiotin synthetase from Escherichia coli catalyses the formation of dethiobiotin from CO2 and 7, 8-diaminopelargonic acid. The reaction is initiated by the formation of a carbamate and proceeds through a phosphorylated intermediate, a mixed carbamic phosphoric anhydride ... Macromolecules Biotin synthase (BioB) (EC 2.8.1.6) is an enzyme that catalyzes the conversion of dethiobiotin (DTB) to biotin; this is the final step in the biotin biosynthetic pathway. Biotin, also known as vitamin B7, is a cofactor used in carboxylation, decarboxylation, and transcarboxylation reactions in many organisms including humans. Biotin synthase is an S-Adenosylmethionine (SAM) dependent enzym…
