Identification
Name: Menaquinol 6
Description:Menaquinol 6 is a polyprenylhydroquinone having a hexaprenyl moiety at position 2 and a methyl group at position 3. It is a substrate for Dimethyl sulfoxide reductase (dmsA). This enzyme catalyzes the reduction of dimethyl sulfoxide (DMSO) to dimethyl sulfide (DMS) using the following reaction: Dimethylsulfide + menaquinone + H2O = dimethylsulfoxide + menaquinol. DMSO reductase serves as the terminal reductase under anaerobic conditions, with DMSO being the terminal electron acceptor. Terminal reductase during anaerobic growth on various sulfoxides and N-oxide compounds. This enzyme allows P. aeruginosa to grow anaerobically on DMSO as respiratory oxidant. Menaquinol 6 is generated by Ubiquinone/menaquinone biosynthesis methyltransferase (ubiE). This enzyme is required for the conversion of demethylmenaquinone (DMKH2) to menaquinone (MKH2) and has the following catalytic activity: A demethylmenaquinone + S-adenosyl-L-methionine = a menaquinol + S-adenosyl-L-homocysteine.
