EC 3.5.1.127

Accepted name: jasmonoyl-L-amino acid hydrolase

Reaction: a jasmonoyl-L-amino acid + H2O = jasmonate + an L-amino acid

Glossary: tuberonic acid = 12-hydroxyjasmonate = {(1R,2R)-3-oxo-2-[(2Z)-5-hydroxypent-2-enyl]cyclopentyl}acetate
jasmonate = {(1R,2R)-3-oxo-2-[(2Z)-pent-2-enyl]cyclopentyl}acetate

Other name(s): IAR3 (gene name); ILL4 (gene name); ILL6 (gene name)

Systematic name: jasmonoyl-L amino acid amidohydrolase

Comments: This entry includes a family of enzymes that recyle jasmonoyl-amino acid conjugates back to jasmonates. The enzymes from Arabidopsis thaliana have been shown to also act on 12-hydroxyjasmonoyl-L-isoleucine, generating tuberonic acid.
