Purification and Characterization of the RecA Protein from Neisseria gonorrhoeae
The strict human pathogen Neisseria gonorrhoeae is the only causative agent of the sexually transmitted infection gonorrhea. The recA gene from N. gonorrhoeae is essential for DNA repair, natural DNA transformation, and pilin antigenic variation, all processes that are important for the pathogenesis and persistence of N. gonorrhoeae in the human population. To understand the biochemical feature...
متن کاملIdentification and purification of a hemoglobin-binding outer membrane protein from Neisseria gonorrhoeae.
The majority of in vitro-grown Neisseria gonorrhoeae strains were unable to use hemoglobin as the sole source of iron for growth (Hgb-), but a minor population was able to do so (Hgb+). The ability of Hgb+ gonococci to utilize hemoglobin as the iron source was associated with the expression of an iron-repressible 89-kDa hemoglobin-binding protein in the outer membrane. The N-terminal amino acid...
متن کاملThe major anaerobically induced outer membrane protein of Neisseria gonorrhoeae, Pan 1, is a lipoprotein.
Pan 1 is an acidic outer membrane protein of Neisseria gonorrhoeae that is expressed only when gonococci are grown anaerobically. On silver-stained sodium dodecyl sulfate-polyacrylamide gels, Pan 1 migrates as an intense but diffuse 54-kDa protein. The deduced amino acid sequence of Pan 1 from the aniA (anaerobically induced protein) open reading frame reveals a lipoprotein consensus sequence, ...
متن کاملThe construction and characterization of Neisseria gonorrhoeae lacking protein III in its outer membrane
Protein III (PIII) is a highly conserved, antigenically stable gonococcal outer membrane protein that is closely associated with the major outer membrane protein, protein I (PI). We have previously reported the cloning of the PIII gene. This gene was inserted into the Eco RI site of the runaway plasmid pMOB45. The beta-lactamase (beta la) Bam HI restriction fragment from the gonococcal plasmid ...
متن کاملPurification and partial characterization of the opacity-associated proteins of Neisseria gonorrhoeae
Gonococci, grown on agar, frequently give rise to opaque colonies. This opacity phenotype is associated with the presence of one or more outer membrane proteins of approximately 28,000 mol weight. These proteins are included within a class of proteins named proteins II. A method is described to isolate and purify the opacity-associated proteins from Neisseria gonorrhoeae. This method uses high ...
