http://purl.uniprot.org/citations/7830550http://www.w3.org/2000/01/rdf-schema#comment"In this report we evaluate the role of catalase in the survival of Bordetella pertussis within human polymorphonuclear leukocytes (PMNs). Crude extracts of B. pertussis exhibited a single catalase activity when subjected to non-denaturing polyacrylamide gel electrophoresis and assayed for catalase activity. A plasmid containing B. pertussis katA was identified by complementation of UM255, a catalase-deficient strain of Escherichia coli. The nucleotide sequence of katA predicts a 55 kDa protein that shares homology with a class of haem-containing catalases found in both eubacteria and eukaryotes. Analysis of the nucleotide sequence upstream of katA revealed the presence of a copy of IS481, a B. pertussis-specific insertion sequence. The start site of transcription of katA was mapped to a T residue in IS481 by primer extension analysis performed with B. pertussis RNA and a katA-specific primer. A catalase-deficient strain of B. pertussis, DD900, was constructed by gene replacement. DD900 was more sensitive to killing by 1 and 5 mM H2O2 than the parental strain, BP339. However, there was no difference in the ability of DD900 and BP339 to survive for 2 h in human PMNs. This suggests that catalase plays no significant role in the survival of B. pertussis within PMNs."xsd:string
