Complete genome sequence of Granulosicoccus antarcticus type strain IMCC3135<SUP>T</SUP>, a marine gammaproteobacterium with a putative dimethylsulfoniopropionate demethylase gene

초록

Granulosicoccus, the only genus of the family Granulosicoccaceae, occupies a distinct phylogenetic position within the order Chromatiales of the Gammaproteobacteria. The genus has been found in various marine regions, especially associated with diverse marine macroalgae. No genomes have been reported for the genus Granulosicoccus thus far, hampering studies on physiology and lifestyles of this genus. Here we report the complete genome sequence of strain IMCC3135(T), the type strain of Granulosicoccus antarcticus isolated from Antarctic coastal seawater. The genome was 7.78 Mbp long and harbored many genes involved in sulfur metabolism. In particular, a gene for dimethylsulfoniopropionate (DMSP) demethylase was found in the genome, rendering strain IMCC3135(T) one of the few marine gammaproteobacteria equipped with the potential for DMSP demethylation.
