Abstract

Methanol assimilation and dissimilation pathways and ammonia assimilation pathway were investigated in four obligate methanol-utilizing bacteria through the detection of key enzymes. Both hexulose phosphate synthetase and hexulose phosphate isomerase, key enzymes of the ribulose monophosphate pathway (RMP) for methanol assimilation were detected whereas four key enzymes (hydroxy pyruvate reductase, isocitrate lyase, malyl-CoA-lyase and glyoxylate aminotransferase) that are characteristic of the serine assimilation pathway were absent. Key enzymes for the two methanol dissimilation pathways, the linear sequence enzymes formaldehyde and formate dehydrogenase and the RMP cyclic sequence enzymes glucose-6-phosphate dehydrogenase and 6-phosphate gluconate dehydrogenase were all detected. Ammonia was assimilated via the glutamate dehydrogenase pathway and not via the glutamine synthetase and glutamate synthase pathway.
