The second subunit of methanol dehydrogenase of Methylobacterium extorquens AM1.
The nucleotide and deduced amino acid sequence of a novel small (beta) subunit of methanol dehydrogenase of Methylobacterium extorquens AM1 (previously Pseudomonas AM1) has been determined. Work with the whole protein has shown that is has an alpha 2 beta 2 configuration.
متن کاملCo-Consumption of Methanol and Succinate by Methylobacterium extorquens AM1
Methylobacterium extorquens AM1 is a facultative methylotrophic Alphaproteobacterium and has been subject to intense study under pure methylotrophic as well as pure heterotrophic growth conditions in the past. Here, we investigated the metabolism of M. extorquens AM1 under mixed substrate conditions, i.e., in the presence of methanol plus succinate. We found that both substrates were co-consume...
متن کاملThe NADP-dependent methylene tetrahydromethanopterin dehydrogenase in Methylobacterium extorquens AM1.
An NADP-dependent methylene tetrahydromethanopterin (H4MPT) dehydrogenase has recently been proposed to be involved in formaldehyde oxidation to CO2 in Methylobacterium extorquens AM1. We report here on the purification of this novel enzyme to apparent homogeneity. Via the N-terminal amino acid sequence, it was identified to be the mtdA gene product. The purified enzyme catalyzed the dehydrogen...
متن کاملFunctional investigation of methanol dehydrogenase-like protein XoxF in Methylobacterium extorquens AM1.
Methanol dehydrogenase-like protein XoxF of Methylobacterium extorquens AM1 exhibits a sequence identity of 50 % to the catalytic subunit MxaF of periplasmic methanol dehydrogenase in the same organism. The latter has been characterized in detail, identified as a pyrroloquinoline quinone (PQQ)-dependent protein, and shown to be essential for growth in the presence of methanol in this methylotro...
متن کاملThe small-subunit polypeptide of methylamine dehydrogenase from Methylobacterium extorquens AM1 has an unusual leader sequence.
The nucleotide sequence for the N-terminal region of the small subunit of methylamine dehydrogenase from Methylobacterium extorquens AM1 has revealed a leader sequence that is unusual in both its length and composition. Gene fusions to lacZ and phoA show that this leader sequence does not function in Escherichia coli but does function in M. extorquens AM1.
