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.[1] 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.
