IUBMB Enzyme Nomenclature


Accepted name: indolylacetylinositol arabinosyltransferase

Reaction: UDP-L-arabinose + (indol-3-yl)acetyl-1D-myo-inositol = UDP + (indol-3-yl)acetyl-myo-inositol 3-L-arabinoside

Other name(s): arabinosylindolylacetylinositol synthase; UDP-L-arabinose:indol-3-ylacetyl-myo-inositol L-arabinosyltransferase; UDP-L-arabinose:(indol-3-yl)acetyl-myo-inositol L-arabinosyltransferase

Systematic name: UDP-L-arabinose:(indol-3-yl)acetyl-1D-myo-inositol L-arabinosyltransferase

Comments: The position of acylation is indeterminate because of the ease of acyl transfer between hydroxy groups. For a diagram showing the biosynthesis of UDP-L-arabinose, click here.
