CRYSTAL STRUCTURE OF THE C-TERMINAL DOMAIN OF BCLA, THE MAJOR ANTIGEN OF THE EXOSPORIUM OF THE BACILLUS ANTHRACIS SPORE.
Overview
The lethal disease anthrax is propagated by spores of Bacillus anthracis, which can penetrate into the mammalian host by inhalation, causing a rapid, progression of the disease and a mostly fatal outcome. We have solved the, three-dimensional structure of the major surface protein BclA on B., anthracis spores. Surprisingly, the structure resembles C1q, the first, component of complement, despite there being no sequence homology., Although most assays for C1q-like activity, including binding to C1q, receptors, suggest that BclA does not mimic C1q, we show that BclA, as, well as C1q, interacts with components of the lung alveolar surfactant, layer. Thus, to better recognize and invade its hosts, this pathogenic, soil bacterium may have evolved a surface protein whose structure is, strikingly close to a mammalian protein.
