COMMENTARY 
LITERATURE
evolution
the sequence determines SlCGT as a GDSL lipase-like protein, representing it as a member of the SGNH protein superfamily. Lipases of this family employ a catalytic triad of Ser-Asp-His with Ser as nucleophile of the GDSL motif. The catalytic triad of the GDSL lipase is not essential for SlCGT enzymatic activity. SlCGT is therefore an example of a GDSL lipase-like protein that has lost hydrolytic activity and has acquired a completely new function in plant metabolism, functioning in secondary metabolism as acyltransferase in synthesis of hydroxycinnamate esters by employing amino acid residues different from the lipase catalytic triad

additional information
the deduced SlCGT amino acid sequence matches the conservation of the serine catalytic motif GXSXXDXG within the first consensus block near the N-terminus. A serine moiety of the GDSL protein may be part of the catalytic center in SlCGT
