CC   -!- FUNCTION: Polymerizes chitin, a structural polymer of the cell wall and
CC       septum, by transferring the sugar moiety of UDP-GlcNAc to the non-
CC       reducing end of the growing chitin polymer. {ECO:0000305}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=[(1->4)-N-acetyl-beta-D-glucosaminyl](n) + UDP-N-acetyl-alpha-
CC         D-glucosamine = [(1->4)-N-acetyl-beta-D-glucosaminyl](n+1) + H(+) +
CC         UDP; Xref=Rhea:RHEA:16637, Rhea:RHEA-COMP:9593, Rhea:RHEA-COMP:9595,

CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the chitin synthase family. {ECO:0000305}.
