HAMAP: Helicobacter acinonychis (strain Sheeba) complete proteome

General information

Species:  Helicobacter acinonychis (strain Sheeba)
Species code: HELAH
Taxonomy: Bacteria; Proteobacteria; Epsilonproteobacteria; Campylobacterales; Helicobacteraceae; Helicobacter (TaxID: 382638) [NEWT/ NCBI]
Description: Helicobacter acinonychis strain Sheeba is the causative agent of severe gastritis in large felines such as tigers, lions and cheetahs. H. acinonychis arose 200000 years ago via a host jump of H.pylori from early humans. Its genome is made up of one chromosome and one plasmid. It possesses a large number of highly fragmented genes, many encoding outer membrane proteins. These genes could have been destroyed in order to bypass deleterious responses from the feline host immune system. Five genes are present that are involved in sialylation of cell surface carbohydrates and that were probably acquired by horizontal gene transfer.
Properties: Presence of flagella: Yes
