Crystal structure of the N-terminal domain of the fibronectin-binding protein PavA from Streptococcus pneumoniae.

ABSTRACT: The Gram-positive bacterium Streptococcus pneumoniae, a major human pathogen, is a regular colonizer of the upper and lower respiratory tracts. Pneumococcal adherence and virulence factor A (PavA), a fibronectin-binding bacterial protein, from S. pneumoniae is an important facilitator of its colonization of host cells. In this study, the crystal structure of the N-terminal domain of PavA (SpPavA-N) determined at a resolution of 2.39?Å is reported. Each monomer of the dimeric protein consists of two domains (domains I and II) and a short ?-helix (?6) at the C-terminus that are connected by elongated loops. Comparison of the SpPavA-N structure with that of its homolog from Streptococcus suis (FBPS-N) revealed differences in ?5, ?6 and the domain II/?6 inter-loop region within domain II. The ?5 helix of FBPS-N folds back toward domain I, whereas in SpPavA-N it adopts an elongated rod shape.
