Genome Sequence of the Methanotrophic Alphaproteobacterium Methylocystis sp. Strain Rockwell (ATCC 49242).

Methylocystis sp. strain Rockwell (ATCC 49242) is an aerobic methane-oxidizing alphaproteobacterium isolated from an aquifer in southern California. Unlike most methanotrophs in the Methylocystaceae family, this strain has a single pmo operon encoding particulate methane monooxygenase but no evidence of the genes encoding soluble methane monooxygenase. This is the first reported genome sequence of a member of the Methylocystis species of the Methylocystaceae family in the order Rhizobiales. [ABSTRACT FROM AUTHOR]
