Abstract:
:The gene encoding the alpha-subunit of methanol dehydrogenase (mxaF) and its flanking region was isolated from a methylotrophic bacterium, Hyphomicrobium methylovorum GM2. The deduced amino acid sequence of MxaF showed 80, 80, 74 and 66% identity with those of Methylobacterium extorquens AM1, M. organophilum XX, Paracoccus denitrificans and Methylophilus methylotrophus, respectively. The putative mxaF promoter sequence (-35 -AAAGACA-, -10 -TAGAA-) observed in other methylotrophs was not found in the region 5' of H. methylovorum GM2 mxaF. Downstream of mxaF, five open reading frames and one partial open reading frame were detected which had high identity with the genes mxaJ, mxaG, mxaI, mxaR, mxaS and mxaA. This indicated the existence of a mxaFJGIRSA gene cluster in H. methylovorum GM2, as previously observed in M. extorquens AM1.
