2-phospho-L-lactate transferase CofD This entry contains 2-phospho-L-lactate transferase (CofD), phosphoenolpyruvate transferase and related sequences. CofD catalyzes 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 flavin derivative found in methanogens, Mycobacteria, and several other lineages. This enzyme is characterized so far in Methanocaldococcus jannaschii (Methanococcus jannaschii) but appears restricted to F420-containing species and is predicted to carry out the same function in these other species. CofD monomer contains 12 beta- strands, seven of them form a Rossmann fold, and 13 alpha-helices.
