L-leucine is a branched-chain amino acid essential for protein synthesis and muscle repair, L-glycine is a small amino acid involved in protein structure and neurotransmission, and L-tyrosine is an aromatic amino acid important for synthesizing neurotransmitters like dopamine and norepinephrine. This tripeptide may be studied for its impact on peptide stability, structure-function relationships in proteins, and potential roles in neurotransmitter-related pathways. It could also be relevant in research focused on amino acid interactions and therapeutic peptide development.

| leukotriene-A4 hydrolase | This is a bifunctional zinc metalloprotease that displays both epoxide hydrolase and aminopeptidase activities. It preferentially cleaves tripeptides at an arginyl bond, with dipeptides and tetrapeptides being poorer substrates (see EC 3.4.11.6, aminopeptidase B). It also converts leukotriene A4 into leukotriene B4, unlike EC 3.3.2.10, soluble epoxide hydrolase, which converts leukotriene A4 into 5,6-dihydroxy-7,9,11,14-icosatetraenoic acid. In vertebrates, five epoxide-hydrolase enzymes have been identified to date: EC 3.3.2.6 (leukotriene A4 hydrolase), EC 3.3.2.7 (hepoxilin-epoxide hydrolase), EC 3.3.2.9 (microsomal epoxide hydrolase), EC 3.3.2.10 (soluble epoxide hydrolase) and EC 3.3.2.11 (cholesterol-5,6-oxide hydrolase).
