    Phosphorylcholine, a crucial component of the pneumococcal cell wall, is essential in bacterial physiology and in human pathogenesis because it binds to serum components of the immune system and acts as a docking station for the family of surface choline-binding proteins. The three-dimensional structure of choline-binding protein F (CbpF), one of the most abundant proteins in the pneumococcal cell wall, has been solved in complex with choline. CbpF shows a new modular structure composed both of consensus and non-consensus choline-binding repeats, distributed along its length, which markedly alter its shape, charge distribution and binding ability, and organizing the protein into two well-defined modules. The carboxy-terminal module is involved in cell wall binding and the amino-terminal module is crucial for inhibition of the autolytic LytC muramidase, providing a regulatory function for pneumococcal autolysis.
