Nucleoside-specific porin (the tsx gene of Escherichia coli) is 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. The protein contains 294 amino acids the first 22 of which are characteristic of a bacterial signal sequence peptide. Tsx shows no significant similarities to general bacterial porins.
