Description

This entry represents 2-phospho-L-lactate transferase or LPPG:Fo 2-phospho-L-lactate transferase (CofD). CofD catalyses the fourth step in the biosynthesis of coenzyme F420, which is the transfer of the 2-phospholactate moiety from lactyl (2) diphospho-(5')guanosine (LPPG) to 7,8-didemethyl-8-hydroxy-5-deazariboflavin (FO) with the formation of the L-lactyl phosphodiester of 7,8-didemethyl-8-hydroxy-5-deazariboflavin (F420-0) and GMP. 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 [PMID: 18252724, PMID: 11888293]. F420 is found in methanogens, Mycobacteria, and several other lineages. This enzyme is characterised so far in Methanocaldococcus jannaschii (Methanococcus jannaschii) [PMID: 11888293] but appears restricted to F420-containing species and is predicted to carry out the same function in these other species.
