N-acetylneuraminate 9-O-acetyltransferase (CASD1)

O-acetyltransferase that catalyzes 9-O-acetylation of sialic acids (PubMed:20947662, PubMed:26169044). Sialic acids are sugars in the reducing end of glycoproteins and glycolipids, and are involved in a variety of processes like cell-cell interactions, host-pathogen recognition (PubMed:20947662, PubMed:26169044).
