Publication Abstract from PubMed

The choline-binding proteins play essential roles in pneumococcal colonization and virulence. It has been suggested that the choline-binding protein J (termed CbpJ; encoded by the gene sp_0378) from Streptococcus pneumoniae TIGR4 involves in the colonization in host and contributes to evasion of neutrophil killing. Here we report the 2.0A crystal structure of CbpJ in complex with choline. CbpJ consists of an N-terminal putative functional domain (N-domain) followed by a C-terminal choline-binding domain (CBD). The N-domain harbors four degenerated choline-binding repeats (CBRs) that lose the capacity of binding to choline, whereas the CBD is composed of seven typical CBRs. Further functional assays showed that the CBD contributes to the pneumococcal adhesion to human lung epithelial cell A549. These findings provide insights into the pneumococcal pathogenesis and broaden our understanding on the functions of choline-binding proteins.
