5-Lipoxygenase-activating protein is required for cellular leukotriene synthesis and is the target of the leukotriene biosynthesis inhibitors MK-886 (3-[1-(p-chlorophenyl)-5-isopropyl-3-tert-butylthio-1H- indol-2-yl]-2,2-dimethylpropanoic acid) and MK-591 (3-[1-(4-chlorobenzyl)-3-(t-butylthio)-5-(quinolin-2-ylmethoxy)-indol-2-yl] - 2,2-dimethylpropanoic acid). Recent studies demonstrate that 5-lipoxygenase-activating protein binds arachidonic acid and stimulates the utilization of this substrate by 5-lipoxygenase. The present study utilizes a radioligand binding assay to assess the affinity of 5-lipoxygenase-activating protein for arachidonic acid and the specificity of the fatty acid binding site on 5-lipoxygenase-activating protein. Our findings demonstrate that the presence of a free carboxyl group on fatty acids or leukotriene biosynthesis inhibitors which interact with 5-lipoxygenase-activating protein is not required for specific binding to the protein. However, the degree of saturation significantly affects the affinity of fatty acids for 5-lipoxygenase-activating protein.
