Pneumococcal bacteriophage-encoded lysins are modular choline binding proteins that have been shown to act as enzymatic antimicrobial agents (enzybiotics) against streptococcal infections. Here we present the crystal structures of the free and choline bound states of the Cpl-1 lysin, encoded by the pneumococcal phage Cp-1. While the catalytic module displays an irregular (beta/alpha)(5)beta(3) barrel, the cell wall-anchoring module is formed by six similar choline binding repeats (ChBrs), arranged into two different structural regions: a left-handed superhelical domain configuring two choline binding sites, and a beta sheet domain that contributes in bringing together the whole structure. Crystallographic and site-directed mutagenesis studies allow us to propose a general catalytic mechanism for the whole glycoside hydrolase family 25. Our work provides the first complete structure of a member of the large family of choline binding proteins and reveals that ChBrs are versatile elements able to tune the evolution and specificity of the pneumococcal surface proteins.

Figure 1. Structure of Modular Cpl-1 Endolysin(A) Stereo representation of Cpl-1 structure with domains colored differently. Catalytic N-terminal, green; linker, orange; CI domain, cyan; CII domain, magenta. Choline molecules are drawn in a ball-and-stick representation.(B) Topology diagram of Cpl-1. Domains are color-coded as in (A) with the antiparallel b8 strand of the catalytic module highlighted in orange. In the choline binding model, the different ChBrs (p1-p6) are labeled.(C) Comparison of the amino acid sequence of the ChBrs and the C-terminal tail in Cpl-1. The structural domain, the repeat number, and their corresponding amino acids are shown on the left. Residues in b strand conformation are shadowed in yellow. Conserved amino acids among the repeats appear in black boxes. Its consensus sequence (>=50%) is shown at the bottom. Upper case indicates 100% conservation.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
