  Domain Name: TypA_BipA
Tyrosine phosphorylated protein A (TypA)/BipA family belongs to ribosome-binding GTPases. BipA is a protein belonging to the ribosome-binding family of GTPases and is widely distributed in bacteria and plants. BipA was originally described as a protein that is induced in Salmonella typhimurium after exposure to bactericidal/permeability-inducing protein (a cationic antimicrobial protein produced by neutrophils), and has since been identified in E. coli as well. The properties thus far described for BipA are related to its role in the process of pathogenesis by enteropathogenic E. coli. It appears to be involved in the regulation of several processes important for infection, including rearrangements of the cytoskeleton of the host, bacterial resistance to host defense peptides, flagellum-mediated cell motility, and expression of K5 capsular genes. It has been proposed that BipA may utilize a novel mechanism to regulate the expression of target genes. In addition, BipA from enteropathogenic E. coli has been shown to be phosphorylated on a tyrosine residue, while BipA from Salmonella and from E. coli K12 strains is not phosphorylated under the conditions assayed. The phosphorylation apparently modifies the rate of nucleotide hydrolysis, with the phosphorylated form showing greatly increased GTPase activity.
