| Outline of Final Research Achievements |
We genetically analyzed the function of multiple methanol dehydrogenase (MDH) -like genes in Methylobacterium species. It was found that Ca-dependent MDH, MxaF and Ln-dependent MDH, XoxF1 were necessary for the growth on methanol and ethanol. Another alcohol dehydrogenase is involved in propanol oxidation. In addition, genetic analysis on MxbD that acts as lanthanide-switch for the expression of mxaF and xoxF has been done. MxbD is necessary for mxaF expression but not for xoxF expression, and spontaneous mutation in HAMP domain in the protein releases the repression of mxaF expression by the presence of XoxF.
