CRYSTAL STRUCTURE OF COTA, AN ENDOSPORE COAT PROTEIN FROM BACILLUS SUBTILIS

Overview

Endospores produced by the Gram-positive soil bacterium Bacillus subtilis, are shielded by a proteinaceous coat formed by over 30 structural, components, which self-assemble into a lamellar inner coat and a thicker, striated electrodense outer coat. The 65-kDa CotA protein is an abundant, component of the outer coat layer. CotA is a highly thermostable laccase, assembly of which into the coat is required for spore resistance against, hydrogen peroxide and UV light. Here, we report the structure of CotA at, 1.7-A resolution, as determined by x-ray crystallography. This is the, first structure of an endospore coat component, and also the first, structure of a bacterial laccase. The overall fold of CotA comprises three, cupredoxin-like domains and includes one mononuclear and one trinuclear, ... [(full description)]
