CC -!- FUNCTION: Catalyzes the N-deacetylation of poly-beta-1,6-N-acetyl-D-
CC glucosamine (PNAG, also referred to as PIA), a biofilm adhesin
CC polysaccharide. N-deacetylation is crucial for attachment of the
CC polysaccharide to the bacterial cell surface; it leads to the
CC introduction of positive charges in the otherwise neutral PIA polymer,
CC allowing electrostatic interactions (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted, cell wall. Note=Attached to the cell
CC surface. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the polysaccharide deacetylase family.
CC {ECO:0000305}.
