Publication Abstract from PubMed

Citrus variegated chlorosis is a disease that attacks economically important citrus plantations and is caused by the plant-pathogenic bacterium Xylella fastidiosa. In this work, the structure of a small heat-shock protein from X. fastidiosa (XfsHSP17.9) is reported. The high-order structures of small heat-shock proteins from other organisms are arranged in the forms of double-disc, hollow-sphere or spherical assemblies. Unexpectedly, the structure reported here reveals a high-order architecture forming a nearly square cavity.

Crystal structure of a small heat-shock protein from Xylella fastidiosa reveals a distinct high-order structure.,Fonseca EM, Scorsato V, Dos Santos ML, Junior AT, Tada SF, Dos Santos CA, de Toledo MA, de Souza AP, Polikarpov I, Aparicio R Acta Crystallogr F Struct Biol Commun. 2017 Apr 1;73(Pt 4):222-227. doi:, 10.1107/S2053230X17004101.
