N-Acetyl-9-O-acetylneuraminic acid

Description

N-Acetyl-9-O-acetylneuraminic acid (alternatively 9-O-acetyl-N-acetylneuraminic acid) is an O acetylated sialic acid identified in human colon by using high-pressure liquid chromatography and gas-liquid chromatography/mass spectrometry (PMID 3623000 ). It also has been suggested that 9-O-acetyl-N-acetylneuraminic acid is an essential component of the cell surface receptor of influenza C virus (PMID 3700379 ).

Enzymes

Enzyme Details

1. RNA 3'-terminal phosphate cyclase

General function:: Involved in ligase activity, forming phosphoric ester bonds
Specific function:: Catalyzes the conversion of 3'-phosphate to a 2',3'-cyclic phosphodiester at the end of RNA. The mechanism of action of the enzyme occurs in 3 steps: (A) adenylation of the enzyme by ATP; (B) transfer of adenylate to an RNA-N3'P to produce RNA-N3'PP5'A; (C) and attack of the adjacent 2'-hydroxyl on the 3'-phosphorus in the diester linkage to produce the cyclic end product. The biological role of this enzyme is unknown but it is likely to function in some aspects of cellular RNA processing.
Gene Name:: RTCA
Uniprot ID:: O00442
Molecular weight:: 40709.05
