Riboflavin biosynthesis protein
WebbThe biosynthesis of one riboflavin molecule requires one molecule of GTP and two molecules of D-ribulose 5-phosphate as substrates. The imidazole ring of GTP is … Prokaryotic riboflavin biosynthesis proteins are also known as the prokaryotic type-I FAD synthetases, which consist of a C-terminal riboflavin kinase (RFK) and an N-terminal FMN-adenylyltransferase (FMNAT). The globular RFK consists of six antiparallel β-sheets that form a β-barrel, and an α-helix adjacent … Visa mer The prokaryotic riboflavin biosynthesis protein is a bifunctional enzyme found in bacteria that catalyzes the phosphorylation of riboflavin into flavin mononucleotide (FMN) and the adenylylation of FMN into flavin adenine dinucleotide Visa mer Riboflavin is converted into catalytically active cofactors FAD and FMN by the actions of riboflavin kinase EC 2.7.1.26, which converts it into … Visa mer Eukaryotes usually have two separate enzymes, while most prokaryotes have a single bifunctional protein that can carry out both catalyses, although exceptions occur in both cases. While eukaryotic monofunctional RFK is orthologous to the bifunctional Visa mer
