CC   -!- FUNCTION: Functions as substrate-specific channel for nucleosides and
CC       deoxynucleosides. Functions also in albicidin uptake and as receptor
CC       for colicin K. {ECO:0000269|PubMed:9043137}.
CC   -!- SUBCELLULAR LOCATION: Cell outer membrane {ECO:0000269|PubMed:9043137};
CC       Multi-pass membrane protein {ECO:0000305|PubMed:9043137}.
CC   -!- SIMILARITY: Belongs to the nucleoside-specific channel-forming outer
CC       membrane porin (Tsx) (TC 1.B.10) family. {ECO:0000305}.
