Abstract

Novel methylene tetrahydromethanopterin (H4MPT) dehydrogenase enzymes, named MtdC, were purified after expressing in Escherichia coli genes from, respectively, Gemmata sp. strain Wa1-1 and environmental DNA originating from unidentified microbial species. The MtdC enzymes were shown to possess high affinities for methylene-H4MPT and NADP but low affinities for methylene tetrahydrofolate or NAD. The substrate range and the kinetic properties revealed by MtdC enzymes distinguish them from the previously characterized bacterial methylene-H4MPT dehydrogenases, MtdA and MtdB. While revealing higher sequence similarity to MtdA enzymes, MtdC enzymes appear to fulfill a function homologous to the function of MtdB, as part of the H4MPT-linked pathway for formaldehyde oxidation/detoxification.
