The conservation between muscle fatty-acid-binding proteins (M-FABP) of Locusta migratoria flight muscle and human skeletal muscle was investigated. The locust M-FABP cDNA (632 bp) was isolated by 5' and 3' rapid amplification of cDNA ends. The identities of the locust and human M-FABP on the cDNA and protein levels were 54% and 42%, respectively. The predicted amino acid sequence of locust M-FABP indicated a molecular mass of 14935 Da and isoelectric point 6.1. The locust M-FABP was expressed in Escherichia coli, purified by (NH4)2SO4 precipitation, anion-exchange and gel-filtration chromatographies and compared with the recombinant human M-FABP with respect to immunological and binding properties. In spite of the high sequence similarity, the proteins did not show immunological cross-reactivity. The binding parameters of locust M-FABP were analyzed with radiolabeled oleic acid by the Lipidex assay and titration microcalorimetry. Both methods revealed a Kd for oleic acid of 0.5 microM and a binding stoichiometry of 1 mol fatty acid/mol FABP. The delta H, delta G and delta S for oleic acid binding were -146 kJ.mol-1 and -36 J.mol-1 and -369 J.mol-1.K-1 respectively. All the information obtained from binding, fluorescence and displacement studies indicated that locust M-FABP has binding characteristics similar to human M-FABP. Finally the recombinant locust M-FABP was crystallized with and without oleic acid. All crystals were trigonal in the P3(1)21 space group. The unit cell dimensions were a = b = 5.89 nm and c = 14.42 nm.
