Identification of regions of the chromosome of Neisseria meningitidis and Neisseria gonorrhoeae which are specific to the pathogenic Neisseria species.
Neisseria meningitidis and Neisseria gonorrhoeae give rise to dramatically different diseases. Their interactions with the host, however, do share common characteristics: they are both human pathogens which do not survive in the environment and which colonize and invade mucosa at their port of entry. It is therefore likely that they have common properties that might not be found in nonpathogeni...
متن کاملNdeI: a restriction endonuclease from Neisseria denitrificans which cleaves DNA at 5'-CATATG-3' sequences.
Type II restriction endonucleases recognize and cleave near specific DNA sequences, usually 4-6 basepair palindromes. They are of fundamental importance as tools for the recombinant DNA technology as they provide the selective cleavages required for the analysis and restructuring of DNA in vitro. The flexibility of these techniques is proportional to the number of DNA sequences which can be cle...
متن کاملOrganization of carbamoyl-phosphate synthase genes in Neisseria gonorrhoeae includes a large, variable intergenic sequence which is also present in other Neisseria species.
The carbamoyl-phosphate synthase (CPS) enzyme in prokaryotes is a heterodimer, encoded by genes commonly called carA and carB. In most prokaryotes examined, these genes are separated by up to 24 bp and are cotranscribed. In Pseudomonas aeruginosa, carA and carB are also co-transcribed, but are separated by 682 bp. We have determined the complete DNA sequence of the carA and carB genes of Neisse...
متن کاملNeisseria gonorrhoeae
Two fi-lactamase-producing strains of Neisseria gonorrhoeae were studied. The substrate profile, molecular weight, and isoelectric point of their ,8-lactamases were similar to those of the TEM-1 enzyme produced by many gram-negative bacilli. The gonococcal f8-lactamase was cell bound during exponential growth and was most likely located in the periplasm. Penicillin hydrolysis was efficient in i...
