General annotation (Comments)

Function

Catalyzes the removal of O-acetyl ester groups from position 9 of the parent sialic acid, N-acetylneuraminic acid.

Catalytic activity

N-acetyl-O-acetylneuraminate + H2O = N-acetylneuraminate + acetate.

Enzyme regulation

Inhibited by diisopropyl fluorophosphate and diethyl-P-nitrophenyl phosphate.

Subunit structure

Disulfide-linked heterodimer of a small subunit and a large subunit.

Subcellular location

Lysosome.

Tissue specificity

Widely expressed.

Post-translational modification

The two subunits are derived from a single precursor by proteolytic cleavage.

Glycosylated.
