1516710-1	1992	Distinction of leukotriene A4 hydrolase and aminopeptidase activities by site-directed mutagenesis at Glu-297.	Glutamic Acid	102-105	leukotriene A4 hydrolase	Homo sapiens	15-39	
1516710-4	1992	Thus, Glu-297 of LTA4 hydrolase is a candidate for the active site of its aminopeptidase activity, while His-296, His-300 and Glu-319 appear to constitute a zinc binding site.	Glutamic Acid	6-9	leukotriene A4 hydrolase	Homo sapiens	17-31	
1516710-7	1992	The mutant E297Q (Glu changed to Gln) conserved LTA4 hydrolase activity but showed little aminopeptidase activity.	Glutamic Acid	18-21	leukotriene A4 hydrolase	Homo sapiens	48-62
