This family includes two enzymes which are involved in menaquinone biosynthesis. One which catalyses the conversion of cyclic de-hypoxanthine futalosine to 1,4-dihydroxy-6-naphthoate, and one which may be involved in the conversion of chorismate to futalosine [1]. These enzymes comprise two domains with alpha/beta structures, a large domain and a small domain. A pocket between the two domains may form the active site, a conserved histidine located within this pocket could be the catalytic base [2].	Domain
