Protein
Probable N-acetylneuraminic acid outer membrane channel protein NanC
Organism
Escherichia coli O6:H1 (strain CFT073 / ATCC 700928 / UPEC)
Function
Outer membrane channel protein allowing the entry of N-acetylneuraminic acid (Neu5Ac, the most abundant sialic acid on host cell surfaces) into the bacteria. NanC proteins form high-conductance channels which are open at low membrane potentials and which have a weak anion selectivity (By similarity).
Similarity
Belongs to the oligogalacturonate-specific porin KdgM (TC 1.B.35) family. NanC subfamily.
