FEATURES

DESCRIPTION

Also known as PUIB_WHEAT, PINB. Acts as a membranotoxin, probably through its antibacterial and antifungal activities, contributing to the defense mechanism of the plant against predators. Forms monovalent cation-selective ion channels in membranes. Has antibacterial activity against the Gram-positive bacteria S.aureus and C.michiganensis, and the Gram-negative bacteria E.coli, P.syringae pv phaseoli, A.tumefaciens and E.carotovora subsp carotovora. Acts synergistically with PINA against bacteria. Contributes to grain texture and hardness.
