DNA Binding
EC Number 3.1.1.32
Enzyme Function FUNCTION: Sn-1-specific phospholipase that releases free fatty acids from phospholipids. Low activity on galactolipids and triacylglycerols. Catalyzes the initial step of jasmonic acid biosynthesis. Not essential for jasmonate biosynthesis after wounding or upon pathogen infection. {ECO:0000269|PubMed:11595796, ECO:0000269|PubMed:18267087, ECO:0000269|PubMed:20348210}.
