1.14.14.49
Accepted name
12-hydroxyjasmonoyl-L-amino acid 12-hydroxylase
Reaction
a 12-hydroxyjasmonoyl-L-amino acid + 2 [reduced NADPH—hemoprotein reductase] + 2 O2 = a 12-hydroxy-12-oxojasmonoyl-L-amino acid + 2 [oxidized NADPH—hemoprotein reductase] + 3 H2O (overall reaction);;(1a) a 12-hydroxyjasmonoyl-L-amino acid + [reduced NADPH—hemoprotein reductase] + O2 = a 12-oxojasmonoyl-L-amino acid + [oxidized NADPH—hemoprotein reductase] + 2 H2O;;(1b) a 12-oxojasmonoyl-L-amino acid + [reduced NADPH—hemoprotein reductase] + O2 = a 12-hydroxy-12-oxojasmonoyl-L-amino acid + [oxidized NADPH—hemoprotein reductase] + H2O
Other name(s)
CYP94C1 (gene name)
Systematic name
12-hydroxyjasmonoyl-L-amino acid,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (12-hydroxylating)
Comment
A cytochrome P450 (heme thiolate) enzyme found in plants. The enzyme acts on jasmonoyl-L-amino acid conjugates that have been hydroxylated at the C-12 position of jasmonic acid by EC 1.14.14.48, jasmonoyl-L-amino acid 12-hydroxylase, further oxidizing that position to a carboxylate via an aldehyde intermediate. While the best studied substrate is (+)-7-epi-jasmonoyl-L-isoleucine, the enzyme was shown to be active with jasmonoyl-L-phenylalanine, and is likely to be active with other jasmonoyl-amino acid conjugates.
