dc.description.abstractWe have previously reported the nucleotide sequence of the Streptococcus pneumoniae type 19F capsular polysaccharide synthesis locus (cps19f), which consists of 15 open reading frames (ORFs) designated cps19fA to -O. Hybridization analysis indicated that close homologs for cps19fA to -H and cps19fK to -O were found in type 19B, but there were no homologs for cps19fI and -J. In this study we used long-range PCR to amplify and clone a 10.5-kb section of the S. pneumoniae type 19B capsule locus (cps19b) between cps19bH and cps19bK. This region of the cps19b locus is 4 kb larger than that in the cps19f locus and replaces cps19fI and cps19fJ with five new ORFs, designated cps19bP, -I, -Q, -R, and -J. We have proposed functions for four of the protein products, including functional homologs of Cps19fI and Cps19fJ. Transformation of a S. pneumoniae mutant containing an interrupted type 19F capsule locus with the 10.5-kb cps19b PCR product converted the recipient strain to type 19B. Southern hybridization analysis indicated that cps19bP, -I, -Q, -R, and -J are unique to type 19B and the closely related type 19C.-
