A marine psychrophilic bacterium _Paenisporosarcina antarctica_ CGMCC 1.6503T (= JCM 14646T) was isolated off King George Island, Antarctica (62°13'31? S 58°57'08? W). In this study, we report the complete genome sequence of _Paenisporosarcina antarctica_, which is comprised of 3,972,524?bp with a mean G?+?C content of 37.0%. By gene function and metabolic pathway analyses, studies showed that strain CGMCC 1.6503T encodes a series of genes related to cold adaptation, including encoding fatty acid desaturases, dioxygenases, antifreeze proteins and cold shock proteins, and possesses several two-component regulatory systems, which could assist this strain in responding to the cold stress, the oxygen stress and the osmotic stress in Antarctica. The complete genome sequence of _P. antarctica_ may provide further insights into the genetic mechanism of cold adaptation for Antarctic marine bacteria.
