IUBMB Comments

Not identical with EC 2.3.1.18 galactoside O-acetyltransferase. The acetyl group is added exclusively to the C6 position of glucose and to the C6 position of the non-reducing glucose residue of maltose . Other substrates of this enzyme are glucose, which is a better substrate than maltose , and mannose and frucose, which are poorer substrates than maltose . Isopropyl-β-thio-galactose, which is a good substrate for EC 2.3.1.118 is a poor substrate for this enzyme .

The expected taxonomic range for this enzyme is: Bacteria, Archaea, Eukaryota

Synonyms
maltose o-acetyltransferase, maltose transacetylase, maa gene product, more
