THE CRYSTAL STRUCTURE OF PGIP (POLYGALACTURONASE INHIBITING PROTEIN), A LEUCINE RICH REPEAT PROTEIN INVOLVED IN PLANT DEFENSE
Overview
Polygalacturonase-inhibiting proteins (PGIPs) are plant cell wall proteins, that protect plants from fungal invasion. They interact with, endopolygalacturonases secreted by phytopathogenic fungi, inhibit their, enzymatic activity, and favor the accumulation of oligogalacturonides, which activate plant defense responses. PGIPs are members of the, leucine-rich repeat (LRR) protein family that in plants play crucial roles, in development, defense against pathogens, and recognition of beneficial, microbes. Here we report the crystal structure at 1.7-A resolution of a, PGIP from Phaseolus vulgaris. The structure is characterized by the, presence of two beta-sheets instead of the single one originally predicted, by modeling studies. The structure also reveals a negatively charged, surface on ...
