Abstract
Together with genome analysis and knock-out mutants, structural and functional characterization of proteins provide valuable hints on the biology of the organism under investigation. Structural characterization can be achieved by techniques such as X-ray crystallography, NMR, Cryo-EM. The information derived from the structure are a good starting point to comprehend the details of the proteins molecular function for a better understanding of their biological role. This review aims at describing the progress in the structural and functional characterization of proteins from the plant pathogen Erwinia amylovora obtained by structural biology and currently deposited in the Protein Data Bank.
