Protein

Leukotriene A-4 hydrolase homolog

Gene

LAP2

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Aminopeptidase that preferentially cleaves tripeptides. Also has low epoxide hydrolase activity (in vitro). Can hydrolyze an epoxide moiety of LTA4 to form LTB4 (in vitro).5 Publications

Catalytic activityi

(7E,9E,11Z,14Z)-(5S,6S)-5,6-epoxyicosa-7,9,11,14-tetraenoate + H2O = (6Z,8E,10E,14Z)-(5S,12R)-5,12-dihydroxyicosa-6,8,10,14-tetraenoate.1 Publication

Cofactori

Binds 1 zinc ion per subunit.1 Publication

Enzyme regulationi

Inhibited 3-(4-benzyloxyphenyl)-2-(R)-amino-1-propanethiol (thioamine) and N-hydroxy-N-(2-(S)-amino-3-(4-benzyloxyphenyl)propyl)-5-carboxypen-tanamide (hydroxamic acid). The aminopeptidase activity is stimulated by LTA4.2 Publications
