A leucine-rich repeat plant protein involved in resistance to pathogens, a polygalacturonase-inhibiting protein (PGIP-1) from Phaseolus vulgaris, has been crystallized and preliminary X-ray characterization has been performed. The protein contains ten repeats of a short (24 amino-acid) leucine-rich repeat motif. Single crystals of the protein were grown from vapour-diffusion experiments using PEG 2K monomethylether as precipitant; these crystals diffract to at least 2.3 A resolution. The space group is P2(1), with two molecules of PGIP-1 in the asymmetric unit; the crystals contain approximately 38% solvent.

Abstract
A leucine-rich repeat plant protein involved in resistance to pathogens, a polygalacturonase-inhibiting protein (PGIP-1) from Phaseolus vulgaris, has been crystallized and preliminary X-ray characterization has been performed. The protein contains ten repeats of a short (24 amino-acid) leucine-rich repeat motif. Single crystals of the protein were grown from vapour-diffusion experiments using PEG 2K monomethylether as precipitant; these crystals diffract to at least 2.3 A resolution. The space group is P2(1), with two molecules of PGIP-1 in the asymmetric unit; the crystals contain approximately 38% solvent.File in questo prodotto:
