Characterization of a multienzyme complex derived from a Bacillus subtilis DNA-membrane extract that synthesizes RNA and DNA precursors

Autor: M Bouyea, I L Skolnik, D A Hadley, William Firshein, J J Laffan

Publikováno v: Journal of Bacteriology. 172:5724-5731

The activity of a variety of enzymes involved in the synthesis of RNA and DNA precursors was found to copurify with initiation of DNA replication activity. These enzymes included ribo- and deoxyribonucleoside kinases, kinases for their phosphorylated

Evaluation of two string tests for obtaining gastric juice for culture, nested-PCR detection, and combined single- and double-stranded conformational polymorphism discrimination of Helicobacter pylori

Autor: D A, Ferguson, C, Jiang, D S, Chi, J J, Laffan, C, Li, E, Thomas

Publikováno v: Digestive diseases and sciences. 44(10)

We have compared two gastric string tests for obtaining gastric juice for culture of Helicobacter pylori and for nested-PCR detection and PCR-based combined single- and double-stranded conformational polymorphism (SDSCP) discrimination of infecting s

Identification of H. pylori in saliva by a nested PCR assay derived from a newly cloned DNA probe

Autor: C, Jiang, C, Li, T, Ha, D A, Ferguson, D S, Chi, J J, Laffan, E, Thomas

Publikováno v: Digestive diseases and sciences. 43(6)

A novel probe was developed from genomic DNA of Helicobacter pylori ATCC type strain 43629. It hybridized with all 73 H. pylori clinical isolates tested but not with any of 183 non-H. pylori DNAs in dot blot hybridization. Typing tests revealed 41 di

A high molecular weight protein from Staphylococcus intermedius cross-reacts with Staphylococcus aureus enterotoxin antibodies

Autor: J J, Laffan, P, Petras, K P, Ferguson, D W, Lambe

Publikováno v: Microbios. 88(357)

Enterotoxin production by Staphylococcus species other than Staphylococcus aureus has been reported. Staphylococcus strains (104 in toto) representing twelve species and subspecies were examined for enterotoxins using a commercial staphylococcal ente

Physical distance between the site of type II DNA binding to the membrane and oriC on the Bacillus subtilis 168 chromosome

Autor: N Sueoka, J J Laffan, Mitsuhiro Itaya

Publikováno v: Journal of bacteriology. 174(16)

The precise physical locations of the oriC region and the region for type II DNA binding to the membrane on the Bacillus subtilis 168 chromosome were determined. The DNA regions were physically mapped by creating new restriction sites (NotI and SfiI)

Temporal expression of a membrane-associated protein putatively involved in repression of initiation of DNA replication in Bacillus subtilis

Autor: William Firshein, J J Laffan, B Eident-Wilkinson, L Mele

A Bacillus subtilis membrane-associated protein that binds specifically to the origin region of DNA replication may act as an inhibitor of DNA replication (J. Laffan and W. Firshein, Proc. Natl. Acad. Sci. USA 85:7452-7456, 1988). This protein, origi

Effects of Retaxin and Insulin on Reproductive Tract Size and Early Fetal Loss in Squalus acanthias 1

Autor: J J Laffan, T J Koob, Ian P. Callard

Publikováno v: Biology of Reproduction. 31:231-238

These experiments demonstrate that both porcine relaxin and bovine insulin can increase the cervical cross-sectional area in Squalus acanthias. When given after estradiol priming, the magnitude of this response is greater. This effect is limited to S
