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 ChEBI:CHEBI:58223; EC=2.4.1.16;
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:16314447};
CC Multi-pass membrane protein {ECO:0000255}. Cytoplasmic vesicle membrane
CC {ECO:0000269|PubMed:17042749}; Multi-pass membrane protein
CC {ECO:0000255}. Note=A constitutive cytoplasmic pool is present that
CC localizes to intracellular microvesicles termed chitosomes. Chitosomes
CC constitute a separate secretory route distinct from the typical
CC secretory pathway and serve as a vehicle for delivering the enzyme to
CC the sites on the cell surface where polysaccharide sythesis takes
CC place. Localizes to septa of yeast-like cells and to the basal septum
CC separating the living tip cell from the vacuolated part in hyphae.
CC {ECO:0000269|PubMed:16314447, ECO:0000269|PubMed:17042749}.
CC -!- SIMILARITY: Belongs to the chitin synthase family. Class I subfamily.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAA61027.1; Type=Frameshift; Evidence={ECO:0000305};
CC Sequence=CAA61027.1; Type=Miscellaneous discrepancy; Note=Internal deletion and contaminating sequence at the C-terminus from position 892 onwards.; Evidence={ECO:0000305};
