| enzymes of dimethylsulfone metabolism and the phylogenetic characterization of the facultative methylotrophs arthrobacter sulfonivorans sp. nov., arthrobacter methylotrophus sp. nov., and hyphomicrobium sulfonivorans sp. nov. | novel methylotrophic arthrobacter and hyphomicrobium species are described. constitutive membrane-associated dimethylsulfone- and dimethylsulfoxide-reductases were found in arthrobacter methylotrophus strain tga and hyphomicrobium sulfonivorans strain s1. enzyme activities increased during growth with dimethylsulfone or dimethylsulfoxide, respectively, and different ratios of activity with different growth substrates indicated that they are separate enzymes. sds-page showed some membrane-associa ... | 2002 | 11807567 |
