IUBMB Enzyme Nomenclature


Accepted name: indoleacetylglucose—inositol O-acyltransferase

Reaction: 1-O-(indol-3-yl)acetyl-β-D-glucose + myo-inositol = D-glucose + O-(indol-3-yl)acetyl-myo-inositol

Other name(s): indole-3-acetyl-β-1-D-glucoside:myo-inositol indoleacetyltransferase; 1-O-(indol-3-ylacetyl)-β-D-glucose:myo-inositol indole-3-ylacetyltransferase

Systematic name: 1-O-(indol-3-yl)acetyl-β-D-glucose:myo-inositol (indol-3-yl)acetyltransferase

Comments: The position of acylation is indeterminate because of the ease of acyl transfer between hydroxy groups.
