Elucidation of cold adaptation in Glaciimonas sp. PAMC28666 with special focus on trehalose biosynthesis
Glaciimonas sp. PAMC28666, an extremophilic bacterium thriving in Antarctic soil and belonging to the Oxalobacteraceae family, represents the only complete genome of its genus available in the NCBI database. Its genome measures 5.2 Mb and comprises 4,476 genes (4,350 protein-coding and 72 non-coding...
