UniProt Comments
Hydrolyzes certain amino acid conjugates of the plant growth regulator indole-3-acetic acid (IAA), including IAA-Phe, IAA-Leu and IAA-Tyr (PubMed:7792599, PubMed:10072397, PubMed:11923288). Can also use IAA-Ala, IAA-Gly, IAA-Met and IAA-Glu as substrates with low efficiency (PubMed:7792599, PubMed:10072397, PubMed:11923288). No activity with IAA-Ile, IAA-1-O-beta-D-glucose or IAA-myo-inositol (PubMed:7792599, PubMed:10072397, PubMed:11923288). Is the most efficient enzyme of the ILL family for IAA-Leu hydrolysis (PubMed:11923288). Important for IAA-Leu and IAA-Phe hydrolysis in roots (PubMed:15155875). May act with ILL2 to provide free IAA to germinating seedlings (PubMed:15155875).
