Nucleoside-specific channel-forming protein, Tsx-like superfamily (IPR036777)

Short name: Channel_Tsx-like_sf

Overlapping entries


The tsx gene of Escherichia coli encodes an outer membrane protein, Tsx, which constitutes the receptor for colicin K and Bacteriophage T6, and functions as a substrate-specific channel for nucleosides and deoxy-nucleosides [PMID: 2265760]. The protein contains 294 amino acids, the first 22 of which are characteristic of a bacterial signal sequence peptide. The putative mature form of Tsx contains 272 residues with a calculated Mr of 31418. The Tsx sequence shows an even distribution of charged residues and lacks extensive hydrophobic stretches [PMID: 2265760]. Tsx shows no significant similarities to the channel-forming proteins OmpC, OmpF, PhoE and LamB from the E. coli outer membrane.
