Background Pseudoalteromonas sp. (strain SM9913) is an aerobic, psychrophilic, deep-sea marine Gram-negative bacterium. It has gene clusters related to both polar and lateral flagella biosynthesis. Lateral flagella, which are usually present in deep-sea bacteria and absent in the related surface bacteria, are important for the survival in deep-sea environments. With these two flagellar systems, Pseudoalteromonas sp. can swim in sea water and swarm on the sediment particle surface, favoring the acquisition of nutrients from particulate organic matter and reflecting its particle-associated alternative lifestyle in the deep sea. A total of 12 genomic islands are identified in its genome that may confer specific features unique to strain SM9913 and absent from strain TAC125, such as drug and heavy metal resistance. Many signal transduction genes and a glycogen production operon are also present in the genome, which may help respond to food pulses and store carbon and energy in a deep-sea environment. It is less tolerant of H2O2 than strain TAC125. (Adapted from PMID: 20703316). (EBI Integr8)
