General Information

General Information Comment Organism
physiological function FbiB produces cofactor F420 with predominantly 5-7 L-glutamate residues in the poly-gamma-glutamate tail, reactions of EC 6.3.2.31 and 6.3.2.34. The N-terminal domain of FbiB is homologous to CofE with an annotated gamma-glutamyl ligase activity, whereas the C-terminal domain has sequence similarity to an FMN-dependent family of nitroreductase enzymes. Communication between the two domains is critical for full gamma-glutamyl ligase activity Mycobacterium tuberculosis
