ID 1.1.99.37 DE methanol dehydrogenase (nicotinoprotein). AN NDMA-dependent methanol dehydrogenase. AN nicotinoprotein methanol dehydrogenase. CA A + methanol = AH2 + formaldehyde. CC -!- Nicotinoprotein methanol dehydrogenases have a tightly bound CC NADP+/NADPH cofactor that does not dissociate during the catalytic CC process. CC -!- Instead, the cofactor is regenerated by a second substrate or CC electron carrier. CC -!- While the in vivo electron acceptor is not known, N,N-dimethyl-4- CC nitrosoaniline (NDMA) can serve this function in vitro. CC -!- The enzyme has been detected in several Gram-positive methylotrophic CC bacteria, including Amycolatopsis methanolica, Rhodococcus CC rhodochrous and Rhodococcus erythropolis. CC -!- These enzymes are decameric, and possess a 5-fold symmetry. CC -!- Some of the enzymes can also dismutate formaldehyde to methanol and CC formate.
