pubmed-article:21602357 | pubmed:abstractText | Pyrococcus sp. strain NA2, isolated from a deep-sea hydrothermal vent sample, is a novel marine hyperthermophilic archaeon that grows optimally at 93 °C. The complete genome sequence of the strain contains all the genes for the tricarboxylic acid cycle except for succinate dehydrogenase/fumarate reductase, but the genome does not encode proteins involved in polysaccharide utilization. | lld:pubmed |
