Enzyme Function FUNCTION: O-acetyltransferase that catalyzes 9-O-acetylation of sialic acids. Sialic acids are sugars at the reducing end of glycoproteins and glycolipids, and are involved in various processes such as cell-cell interactions, host-pathogen recognition. {ECO:0000250|UniProtKB:Q96PB1}.
