| Accepted name: |
jasmonic acid 12-hydroxylase |
| Reaction: |
(–)-jasmonate + NADPH + H+ + O2 = trans-12-hydroxyjasmonate + NADP+ + H2O |
| Glossary: |
(–)-jasmonate = {(1R,2R)-3-oxo-2-[(2Z)-pent-2-en-1-yl]cyclopentyl}acetate
trans-12-hydroxyjasmonate = {(1R,2R)-2-[(2Z)-5-hydroxypent-2-en-1-yl]-3-oxocyclopentyl}acetate |
| Other name(s): |
ABM (gene name) |
| Systematic name: |
jasmonate,NADPH:oxygen oxidoreductase (12-hydroxylating) |
| Comments: |
Although believed to occur in plants, the enzyme has so far been characterized only from the rice blast fungus, Magnaporthe oryzae. The fungus strategically deploys the enzyme to hydroxylate and inactivate endogenous jasmonate to evade the jasmonate-based innate immunity in rice plants. |

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)-2-[(2Z)-5-hydroxypent-2-enyl]-3-oxo-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. |
