ID 1.14.15.38 DE N,N-dimethyl phenylurea N-demethylase. CA a 1,1-dimethyl-3-phenylurea + 2 H(+) + O2 + 2 reduced [2Fe-2S]- CA [ferredoxin] = a 1-methyl-3-phenylurea + formaldehyde + H2O + 2 oxidized CA [2Fe-2S]-[ferredoxin]. CC -!- The enzyme, found in members of the Sphingobium genus, initiates the CC degradation of N,N-dimethyl-phenylurea herbicides by mono-N- CC demethylation. CC -!- The catalytic unit contains a Rieske [2Fe-2S] iron-sulfur cluster, CC and catalyzes the monooxygenation of a methyl group. CC -!- The resulting N-methoxyl group is unstable and decomposes CC spontaneously to form formaldehyde. CC -!- The enzyme associates with additional proteins (a reductase and a CC [3Fe-4S] type ferredoxin) that are involved in the transfer of CC electrons from NAD(P)H to the active site.
