Summation

A flavin monooxygenase-like enzyme (YUCCA like) converts Indol-3-pyruvic acid to Indol-3-acitic acid.
It is demonstrated that by a quantification method of IPA using liquid chromatography-electrospray ionization-tandem MS that YUC family functions in the conversion of IPA to IAA in Arabidopsis (Arabidopsis thaliana). It is empirically proven that YUC protein expressed in Escherichia coli directly converts IPA to IAA. Indole-3-acetaldehyde is probably not a precursor of IAA in the IPA pathway. It is indicated that YUC proteins catalyze a rate-limiting step of the IPA pathway, which is the main IAA biosynthesis pathway in Arabidopsis
