LPPG:FO 2-phospho-L-lactate transferase; important in F420 biosynthesis
CofD is a 2-phospho-L-lactate transferase that catalyzes the last step in the biosynthesis of coenzyme F(420)-0 (F(420) without polyglutamate) by transferring the lactyl phosphate moiety of lactyl(2)diphospho-(5')guanosine (LPPG) to 7,8-didemethyl-8-hydroxy-5-deazariboflavin ribitol (F0). F420 is a hydride carrier, important for energy metabolism of methanogenic archaea, as well as for the biosynthesis of other natural products, like tetracycline in Streptomyces. F420 and some of its precursors are also utilized as cofactors for enzymes, like DNA photolyase in Mycobacterium tuberculosis.
