Catalyzes the conversion of long-chain fatty acids to their active form acyl-CoA for both synthesis of cellular lipids, and degradation via beta-oxidation. Preferentially activates arachidonate and eicosapentaenoate as substrates. Preferentially activates 8,9-EET > 14,15-EET > 5,6-EET > 11,12-EET. Modulates glucose-stimulated insulin secretion by regulating the levels of unesterified EETs. Modulates prostaglandin E2 secretion. Source: Recombinant protein corresponding to aa100-581 from mouse Long-chain-fatty-acid--CoA ligase 4, fused to 6X His-Tag at N-terminal, expressed in E.coli.
