10673221-5	2000	The Arg-51 in LTC4 synthase has been suggested to function as proton donor for the opening of the LTA4 epoxide.	Epoxy Compounds	103-110	leukotriene C4 synthase	Homo sapiens	14-27	
12895593-6	2003	Site-directed mutagenesis of LTC(4) synthase suggests that Arg-51 is involved in opening the epoxide ring of LTA(4) and Tyr-93 in GSH thiolate anion formation during catalytic conjugation.	Epoxy Compounds	93-100	leukotriene C4 synthase	Homo sapiens	29-44	
9153254-9	1997	These results suggest that in the catalytic function of LTC4S, Arg-51 probably opens the epoxide ring and Tyr-93 provides the thiolate anion of GSH.	Epoxy Compounds	89-96	leukotriene C4 synthase	Homo sapiens	56-61
