This family of GCN5-related N-acetyl-transferases bind both CoA and acetyl-CoA. They are characterised by highly conserved glycine, a cysteine residue in the acetyl-CoA binding site near the acetyl group, their small size compared with other GNATs and a lack of of an obvious substrate-binding site. It is proposed that they transfer an acetyl group from acetyl-CoA to one or more unidentified aliphatic amines via an acetyl (cysteine) enzyme intermediate. The substrate might be another macromolecule.
