Abstract

Summary

Barbourin is a 73 amino acid venom protein that inhibits platelet aggregation. Recombinant barbourin (BARH₆), rabbit serum albumin (RSAH₆), and a barbourin-RSA fusion protein (barbourin-linker-albumin; BLAH₆) were secreted from Pichia pastoris yeast, and purified by nickel-chelate affinity chromatography via their C-terminal hexahisti-dine (H₆) tags. BARH₆ and BLAH₆ did not differ in their IC₅₀s for inhibition of platelet aggregation using either human platelets stimulated with thrombin or ADP, or rabbit platelets stimulated with ADP. BARH₆ and BLAH₆ were also effective in inhibiting platelet aggregation in whole blood, and formed complexes with platelet integrin α_IIbβ₃. The terminal catabolic half-life of BLAH₆ approached that of RSAH₆[3.4 ± 0.2 versus 4.0 ± 0.1 days (n = 4 ± SD)], but was substantially increased relative to that of BARH₆ [0.15 ± 0.03 days (n = 3 ± SD)]. Our results suggest that fusion to albumin slows the clearance of barbourin in vivo, while preserving its ability to inhibit platelet aggregation.
