   6.2.1.B3 | evolution |
the 4-coumarate-CoA ligase-like enzyme is a member of the acyl-activating enzyme (AAE) gene family |
722649 |
| 6.2.1.B3 | malfunction |
in response to wounding, opcl1 null mutants exhibit reduced levels of jasmonic acid and hyperaccumulation of OPC-8:0 |
722649 |
| 6.2.1.B3 | metabolism |
the enzyme catalyzes the formation of 3-oxo-2-(2'-[Z]-pentenyl)cyclopentane-1-octanoyl-CoA, which is subsequently converted to jasmonic acid via three beta-oxidation steps |

| 6.2.1.B3 | physiological function |
in response to wounding, null mutants exhibit reduced levels of jasmonic acid and hyperaccumulation of 3-oxo-2-(2-[Z]-pentenyl)cyclopentane-1-octanoic acid. Physiological role for the enzyme in the activation of jasmonic acid biosynthetic precursors in leaf peroxisomes, 3-oxo-2-(2-[Z]-pentenyl)cyclopentane-1-octanoic acid is a physiological substrate for the activation step |
722649 |
| 6.2.1.B3 | physiological function |
mutants exhibit 3-oxo-2(2'-[Z]-pentenyl)cyclopentane-1-octanoic acid accumulation and reduced levels of jasmonic acid. Enzyme catalyzes an essential step in jasmonic acid biosynthesis by initiating the beta-oxidative chain shortening of the carboxylic acid side chain of its precursors |

| 6.2.1.B3 | physiological function |
physiological role for the enzyme in the activation of jasmonic acid biosynthetic precursors in leaf peroxisomes, 3-oxo-2-(2'-[Z]-pentenyl)cyclopentane-1-octanoate is a physiological substrate for the activation step. Coordinated expression of OPCL1, OPR3, and specific beta-oxidation isozymes (e.g., ACX1) in wounded leaves may enhance jasmonate biosynthetic capacity of plants faced with biotic stress |

| 6.2.1.B3 | physiological function |
physiological role for the enzyme in the activation of jasmonic acid biosynthetic precursors in leaf peroxisomes, 3-oxo-2-(2'-[Z]-pentenyl)cyclopentane-1-octanoate is a physiological substrate for the activation step. Wound-induced expression of OPCL1 and OPR3, EC 1.3.1.42, is coregulated by the jasmonate signaling pathway. The inability of OPCL1 to discriminate between 12-oxo-phytodienoate and 3-oxo-2-(2'-[Z]-pentenyl)cyclopentane-1-octanoate suggests that specificity in the biosynthetic pathway is achieved by other mechanisms |
