CC   -!- FUNCTION: N-acetylglucosaminyltransferase that catalyzes the
CC       polymerization of single monomer units of UDP-N-acetylglucosamine to
CC       produce the linear homomer poly-beta-1,6-N-acetyl-D-glucosamine (PNAG,
CC       also referred to as PIA), a biofilm adhesin polysaccharide. Requires
CC       IcaD for full activity (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC       protein {ECO:0000250}.
CC   -!- MISCELLANEOUS: In strain COL, the gene icaC is interrupted by a natural
CC       frameshift.
CC   -!- SIMILARITY: Belongs to the glycosyltransferase 2 family. {ECO:0000305}.
