Peptides with a molecular weight of 5 kDa have been isolated from seeds of
the pinto bean and red bean, respectively. The peptides manifest an N-termi
nal sequence with remarkable resemblance to those of cowpea 10-kDa protein
precursor and garden pea disease resistance response protein. The bean pept
ides possess potent antifungal activity toward a variety of fungal species
including Botrytis cinerea, Mycosphaerella arachidicola, and Fusarium oxysp
orum. The proteins also demonstrate mitogenic activity toward mouse splenoc
ytes and an inhibitory action on HIV-1 reverse transcriptase. (C) 2001 Acad
