Regulation of enterobacterial cephalosporinase production: the role of a membrane-bound sensory transducer

In clinical isolates of Enterobacter cloacae, resistance to the newer beta-lactam antibiotics often results from overproduction of a cephalosporinase encoded by the beta-lactam-inducible ampC gene. Regulation of ampC is controlled by the divergently expres ...

Transcription of the sulA-ompA region of Escherichia coli during the SOS response and the role of an antisense RNA molecule

The transcriptional pattern of the 22 min region of the Escherichia coli chromosome containing the linked sulA and ompA genes, which encode an SOS-inducible inhibitor of cell division and a constitutively expressed, major outer membrane protein, respective ...

Studies of UV-inducible promoters from Clostridium perfringens in vivo and in vitro

Expression of a 4 kb segment of the bacteriocinogenic plasmid, pIP404, from Clostridium perfringens is inducible by UV-irradiation. DNA sequence analysis revealed that this region contains three genes: uviA, uviB and bcn encoding the bacteriocin BCN5. Bioc ...

Nucleotide sequence and transcriptional startpoint of the glpT gene of Escherichia coli: extensive sequence homology of the glycerol-3-phosphate transport protein with components of the hexose-6-phosphate transport system

Stewart Cole

The nucleotide sequences of the glpT gene of Escherichia coli and its regulatory region have been elucidated and the primary structure of the glycerol-3-phosphate transport protein deduced. Extensive amino acid sequence homology was found with two other cy ...

Genome organization of the anaerobic pathogen Clostridium perfringens

A physical map of the genome of Clostridium perfringens, an important human pathogen, has been established by pulsed-field gel electrophoresis. Recognition sites for six rare-cutting endonucleases were situated on a single circular chromosome of approximat ...

1989

In enteric bacteria, the expression of many genes encoding various anaerobic electron transfer functions is controlled by FNR, the product of the autoregulated fnr gene. FNR is structurally and functionally homologous to CAP, the catabolite gene activator ...

Molecular genetic analysis of FNR-dependent promoters

Nucleotide sequence of the dmsABC operon encoding the anaerobic dimethylsulphoxide reductase of Escherichia coli

The nucleotide sequence of a 6.5 kilobasepair chromosomal DNA fragment encoding the anaerobic dimethylsulphoxide (DMSO) reductase operon of Escherichia coli has been determined. The DMSO reductase structural operon was shown to consist of three open readin ...

Nucleotide sequence and gene-polypeptide relationships of the glpABC operon encoding the anaerobic sn-glycerol-3-phosphate dehydrogenase of Escherichia coli K-12.

The nucleotide sequence of a 4.8-kilobase SacII-PstI fragment encoding the anaerobic glycerol-3-phosphate dehydrogenase operon of Escherichia coli has been determined. The operon consists of three open reading frames, glpABC, encoding polypeptides of molec ...

Identification and molecular genetic analysis of replication functions of the bacteriocinogenic plasmid pIP404 from Clostridium perfringens

The replication functions of the bacteriocinogenic plasmid pIP404, from Clostridium perfringens, were localized to a 2.8-kb EcoRI-EcoRV fragment by cloning into a vector deficient for replication in Bacillus subtilis. This fragment contains two genes, cop ...

1988

The complete nucleotide sequence of the bacteriocinogenic plasmid, pIP404, from Clostridium perfringens has been determined. The plasmid genome comprises 10,207 bp and has a dA + dT content of 75%. Functions have been tentatively assigned to 6 of the 10 op ...
