YkgEFG is homologous to the B. subtilis LutABC oxidative lactate catabolism putative electron chain, but ykgEFG does not complement lutABC, perhaps indicating a lactate-related compound is catabolized by YkgEFG; a ykgF mutant is still able to utilize lactate, presumably utilizing LldPRD function (Chai, 2009). YkfG is comprised of a LutC family domain (Pfam PF02589); the N-terminal domain of LutB is a LutC-like domain; the LutC family domain (Pfam PF02589) belongs to a 5-formyltetrahydrofolate cyclo-ligase-like superfamily (InterPro IPR024185) and a NagB/RpiA/CoA transferase-like structural clan (Superfamily SSF100950).
