The A protein of the filamentous bacteriophage Cf of Xanthomonas campestris pv. citri.
Filamentous bacteriophages have very strict host specificities. Experiments were performed to investigate whether the A protein of the filamentous phage Cf, which infects Xanthomonas campestris pv. citri but not X. campestris pv. oryzae, is involved in determining Cf's host specificity. The gene encoding the A protein of Cf was cloned and expressed in X. campestris pv. citri. The genomic DNA of...
متن کاملStructure of proline iminopeptidase from Xanthomonas campestris pv. citri: a prototype for the prolyl oligopeptidase family.
The proline iminopeptidase from Xanthomonas campestris pv. citri is a serine peptidase that catalyses the removal of N-terminal proline residues from peptides with high specificity. We have solved its three-dimensional structure by multiple isomorphous replacement and refined it to a crystallographic R-factor of 19.2% using X-ray data to 2.7 A resolution. The protein is folded into two contiguo...
متن کاملBiological role of xanthomonadin pigments in Xanthomonas campestris pv. campestris.
Previous studies have indicated that the yellow pigments (xanthomonadins) produced by phytopathogenic Xanthomonas bacteria are unimportant during pathogenesis but may be important for protection against photobiological damage. We used a Xanthomonas campestris pv. campestris parent strain, single-site transposon insertion mutant strains, and chromosomally restored mutant strains to define the bi...
متن کاملGenome Sequence of Xanthomonas campestris pv. campestris Strain Xca5
An annotated high-quality draft genome sequence for Xanthomonas campestris pv. campestris race 1 strain Xca5 (originally described as X. campestris pv. armoraciae), the causal agent of black rot on Brassicaceae plants, has been determined. This genome sequence is a valuable resource for comparative genomics within the campestris pathovar.
متن کاملPolymerase chain reaction method for the rapid detection of virulent Shigella spp.
Bacillary dysentery, or shigellosis, is a disease of humans in which the colonic epithelium is invaded by bacteria and subjected to inflammatory destruction. The aim of this study was to develop a polymerase chain reaction(PCR) test for detection of virulent Shigella spp.. For this purpose, the primers were designed to amplify a 526-bp internal region of the Shigella spp. icsA gene, which encod...
