Common NameBiotinyl-5'-AMP
Description5'-biotinyl-AMP (B-AMP) is the active form of biotin. Biotin is essential to maintain metabolic homeostasis and as regulator of gene expression. The vitamin biotin plays an essential role in gluconeogenesis, fatty acid synthesis, and carbohydrate metabolism because of its role as cofactor of five carboxylases; pyruvate carboxylase (PC), propionyl-CoA carboxylase (PCC), methylcrotonyl-CoA carboxylase, and two forms of acetyl-CoA carboxylase (ACC-1 and ACC-2). Carboxylase biotinylation is catalyzed by the enzyme holocarboxylase synthetase (HCS) through a reaction that involves the transformation of biotin into B-AMP and its subsequent attachment to a specific lysine residue in the carboxylases. B-AMP is also required to activate a signal transduction cascade that includes a soluble guanylate cyclase (sGC) and cGMP-dependent protein kinase (PKG). The regulatory role of biotin in the biotin cycle seems to be limited to the expression of proteins involved in the transport and utilization of exogenous vitamin while having no effect on biotinidase mRNA levels, enzyme responsible for biotin recycling during carboxylase turnover.
