Protein Domain : IPR010104

Type:  Family Name:  Bacterial TonB-dependent receptor
Description:  This entry represents a family of TonB-dependent outer-membrane receptors which are found mainly in Xanthomonas and Caulobacter. These appear to represent the expansion of a paralogous family in that the 22 Xanthomonas axonopodis(21 in Xanthomonas campestris) and 18 Caulobacter crescentus(Caulobacter vibrioides) sequences are more closely related to each other than any of the many TonB-dependent receptors found in other species. In fact, the C. crescentus and Xanthomonas sequences are inseparable on a phylogenetic tree using a PAM-weighted neighbour-joining method, indicating that one of the two genuses may have acquired this set of receptors from the other. The mechanism by which this family is shared between Xanthomonas, a gamma proteobacterial plant pathogen and Caulobacter, an alpha proteobacterial aquatic organism is unclear. Short Name:  TonB_rcpt_bac
