| - | ''Fusarium solani'' causes stem and fruit rot disease in ''Capsicum sp.'' causing severe losses. Use of peptides as antimicrobials has been reported earlier. The peptide designing for a specific fungus using its own protein (enzyme) may be a useful strategy for the control of disease. Polyamine biosynthesis is responsible for growth of ''Fusarium solani''. The rate-limiting step of this process is decarboxylation of ornithine. [http://en.wikipedia.org/wiki/Ornithine_decarboxylase Ornithine decarboxylase] (ODC) [http://www.brenda-enzymes.info/php/result_flat.php4?ecno=4.1.1.17 (EC 4.1.1.17)] is an enzyme that catalyzes the decarboxylation of ornithine to putrescine. <scene name='Journal:JBSD:8/Cv/9'>Ornithine</scene> is an amino acid, whereas <scene name='Journal:JBSD:8/Cv/5'>putrescine</scene> is a polyamine.

In this study, we designed 15 peptide inhibitors by the random alteration of active site residues at which ornithine binds. These inhibitors were peptides of the length of nine residues. The peptide, <scene name='Journal:JBSD:8/Cv/7'>GLIWGNGPF showed highest docking with active site of ODC</scene>, which is four times greater than ornithine. Thus, peptides can be used as a potential inhibitor to block the pathway responsible for the growth of the pathogen. | In this study, we designed 15 peptide inhibitors by the random alteration of active site residues at which ornithine binds.
