Protein involved in the synthesis of menaquinone, a derivative of 2-methyl-1,4-naphthoquinone in which the 3-position is substituted with a variable-length polyisoprene chain. In mammals, menaquinone is an important component of the blood coagulation system. Mammals need to obtain this vitamin by their diet or from the bacterial flora of the gut.
