WebBiotin consists of two fused heterocyclic rings and a pentanoate side chain, derived from a pimelate -like structure. The early steps of the pathway, which are described here, are responsible for the synthesis of the precursor of the pimelate moiety in the bacterium Escherichia coli. WebBiotin ligase BirA controls biotin synthesis in Escherichia coli. It sends biotin to metabolism. As a homodimer, it negatively controls the biotin synthetic operon. BirA also catalyzes post-translational biotinylation, by associating with biotin acceptor protein of acetyl-coenzyme A carboxylase. [ 1] [ 2] It can biotinylate human histones. [ 3]
