By a combination of X-ray crystallography, NMR, molecular dynamics techniques and in vivo virulence and phagocytosis studies, we provide structural information of choline-binding protein L (CbpL) and demonstrate its impact on pneumococcal pathogenesis and immune evasion. CbpL is a very elongated three-module protein composed of (i) an Excalibur Ca2+-binding domain -reported in this work for the very first time-, (ii) an unprecedented anchorage module showing alternate disposition of canonical and non-canonical choline-binding sites that allows vine-like binding of fully-PCho-substituted teichoic acids (with two choline moieties per unit), and (iii) a Ltp_Lipoprotein domain. Our structural and infection assays indicate an important role of the whole multimodular protein allowing both to locate CbpL at specific places on the cell wall and to interact with host components in order to facilitate pneumococcal lung infection and transmigration from nasopharynx to the lungs and blood. CbpL implication in both resistance against killing by phagocytes and pneumococcal pathogenesis further postulate this surface-protein as relevant among the pathogenic arsenal of the pneumococcus.","19 Seiten","https://refubium.fu-berlin.de/handle/fub188/21092||http://dx.doi.org/10.17169/refubium-24389","eng","http://creativecommons.org/licenses/by/4.0/","Pathogens||X-ray crystallography","500 Naturwissenschaften und Mathematik::570 Biowissenschaften; Biologie","Modular Architecture and Unique Teichoic Acid Recognition Features of Choline- Binding Protein L (CbpL) Contributing to Pneumococcal Pathogenesis","Wissenschaftlicher Artikel","open access","Scientific Reports. - 6 (2016), Artikel Nr. 38094","10.1038/srep38094","http://www.nature.com/articles/srep38094?WT.feed_name=subjects_biochemistry","2045-2322","Biologie, Chemie, Pharmazie","FUDOCS_derivate_000000007504","FUDOCS_document_000000026117","Der Artikel wurde in einer Open-Access-Zeitschrift publiziert.","no"
