ID 1.14.13.245 DE assimilatory dimethylsulfide S-monooxygenase. CA (1) dimethyl sulfide + H(+) + NADH + O2 = dimethyl sulfoxide + H2O + CA NAD(+). CA (2) dimethyl sulfoxide + H(+) + NADH + O2 = dimethyl sulfone + H2O + CA NAD(+). CC -!- The enzyme, studied from the bacterium Acinetobacter sp. strain 20B, CC is very similar to EC 1.14.13.244. CC -!- It consists of a multisubunit oxygenease component that contains the CC active site and a dinuclear iron center, a reductase component that CC contains FAD and one iron-sulfur cluster, and a regulatory component. CC -!- The three components comprise five different polypeptides. CC -!- The enzyme catalyzes the first two steps of a dimethyl sulfide CC oxidation pathway in this organism. //
