9760176-4	1998	The labeling of 5-lipoxygenase by azido-125I-KBA strictly depended on the presence of calcium ([Ca2+]free > 500 nM) and was abolished by heat denaturation or by prior incubation with a series of pentacyclic triterpenes (e.g., amyrin, beta-boswellic acid, AKBA and 18a-glycyrrhetinic acid).	beta-amyrin	229-235	arachidonate 5-lipoxygenase	Homo sapiens	16-30
