Abstract

Pheromone Receptor Pre-A (PRP-A) is a G Protein-coupled receptor (G-PCR protein with seven transmembrane helices) in Aspergillus flavus, a filamentous fungus known for its aflatoxin production, germination and quorum sensing. It causes an aspergillosis in human beings and domestic animals. With an aim to find a better inhibitor against biosynthesis of aflatoxin, the integral protein structure was effectively engineered, designed, screening against various antifungal compound databases. The LibDock protein-ligand interaction of DSv3.5 study suggests that blasticidin S, pipernonaline and piperin, inhibit PRP-A protein with highest binding affinity. The amino acids frequently involved in binding with the ligand blasticidin S of O2 and H33 and H234 at Arg 400 and Tyr 394 respectively. Our in silico prediction may lead to establish better therapeutic approaches for the treatment against aspergillosis.
