Abstract
The gene cluster for methylamine utilization (mau genes) has been cloned from the obligate methylotrophic bacterium Methylobacillus flagellatum KT. Partial sequence data showed that the organization of these genes was similar to that found in Methylophilus methylotrophus W3A1-NS, including the lack of a gene for amicyanin, which had been thought to be the electron acceptor for methylamine dehydrogenase in M. flagellatum KT. However, a gene encoding azurin was discovered at the 3' end of the mau gene cluster, transcribed in the opposite orientation. A mutant with a defect in this gene showed impaired growth on methylamine, suggesting that azurin is involved in methylamine oxidation in M. flagellatum KT.
