GSID: HLZKuv-_4N0J
WG Coleman Jr, L Leive - Journal of bacteriology, 1979 - Am Soc Microbiol

… Two genetically distinct classes of novobiocin-supersensitive mutants were isolated from Escherichia coli K-12. One class, given the phenotypic name NbsA, lies at 10 min on the E. coli chromosome. … The Escherichia coli K-12 strains used in this...

Envelope Stress Responses.

EcoSal Plus

Macritchie DM, Raivio TL.
PMID: 26443759
EcoSal Plus. 2009 Aug;3(2). doi: 10.1128/ecosalplus.5.4.7.

The gram-negative bacterial envelope is a complex extracytoplasmic compartment responsible for numerous cellular processes. Among its most important functions is its service as the protective layer separating the cytoplasmic space from the ever-changing external environment. To adapt to the...

Pea chloroplast topoisomerase I: purification, characterization, and role in replication.

Plant molecular biology

Nielsen BL, Tewari KK.
PMID: 24272153
Plant Mol Biol. 1988 Jan;11(1):3-14. doi: 10.1007/BF00016009.

A DNA-relaxing enzyme was purified 5 000-fold to homogeneity from isolated chloroplasts of Pisum sativum. The enzyme consists of a single polypeptide of 112 kDa. The enzyme was able to relax negatively supercoiled DNA in the absence of ATP....

STAPHYLOCOCCAL TRANSDUCING PARTICLE.

Journal of bacteriology

Dowell CE, Rosenblum ED.
PMID: 16561970
J Bacteriol. 1962 Nov;84(5):1076-9. doi: 10.1128/jb.84.5.1076-1079.1962.

Dowell, C. E. (The University of Texas, Dallas) and E. D. Rosenblum. Staphylococcal transducing particle. J. Bacteriol. 84:1076-1079. 1962.-When novobiocin-resistant transductants were isolated under conditions that permitted superinfection, almost all the clones were lysogenic for the transducing phage. If...

Effect of mg and ethylenediaminetetraacetate on the in vitro activity of coumermycin a(1) and novobiocin against gram-negative bacteria.

The effect of Mg(2+) and ethylenediaminetetraacetic acid (EDTA) on the in vitro activity of coumermycin A(1) and novobiocin was determined against Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, and Proteus mirabilis grown in Trypticase Soy Broth or defined synthetic medium....

Direct in situ nucleic acid amplification: control of artefact and use of labelled primers.

Clinical molecular pathology

Ray R, Sim R, Khan K, Cooper P, Pounder R, Wakefield A.
PMID: 16696101
Clin Mol Pathol. 1996 Dec;49(6):M345-50. doi: 10.1136/mp.49.6.m345.

Aims-To evaluate factors which ameliorate false positive artefacts with direct in situ PCR using labelled dNTPs; to investigate the use of labelled primers to overcome this artefact whilst maintaining sensitivity.Methods-Sections of measles (RNA virus) infected Vero cells with cytoplasmic...

The cell wall of Bacillus licheniformis N.C.T.C. 6346: Biosynthesis of the teichuronic acid.

The Biochemical journal

Hughes RC.

Biochem J. 1966 Dec;101(3):692-7. doi: 10.1042/bj1010692.

1. Particulate fractions prepared from disrupted cells of Bacillus licheniformis N.C.T.C. 6346 catalyse the uptake of radioactivity from UDP-[(14)C]glucuronic acid or UDP-N[(14)C]-acetylglucosamine. Maximal uptake requires the presence of both nucleotides and Mg(2+) ions. The reaction is inhibited markedly by...

Hydrogen sulfide-producing strains of salmonellae, Escherichia coli, Citrobacter freundii, and Proteus mirabilis were isolated from fresh pork sausage. All the strains produced black-centered colonies on Hektoen enteric agar (HE). On xylose lysine deoxycholate agar (XLD), C. freundii produced yellow...
