Septic Shock With Micrococcus luteus

Archives of Internal Medicine, 1978
Micrococcus luteusis considered a non-pathogenic saprophyte of human skin and eye. Disease in man caused by this organism is not recorded in medical literature. We present a case of septic shock cause byM luteus. The value of this report is to document the pathogenicity of coagulase-negative staphylococci in patients without valvular heart disease ...

Unassigned or Nonsense Codons in Micrococcus luteus

Journal of Molecular Biology, 1993
We previously reported that in Micrococcus luteus, a Gram-positive eubacterium with high genomic G + C content, certain codons ending with A did not appear in coding frames, including termination sites, and tRNAs that translate these codons were not detected. These facts suggest that at least some of them are unassigned (nonsense) codons, i.e.

Electrodiffusion of ethidium cation into Micrococcus luteus cells

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1994
Ethidium bromide fluorescence increased in the presence of Micrococcus luteus cells; this was shown to be due to the interaction of the ethidium cation (Eth) with intracellular nucleic acids. Eth permeation across the cytoplasmic membrane was the rate-limiting step and obeyed first-order kinetics.

Inhibition of diptheroid esterase by Micrococcus luteus

Canadian Journal of Microbiology, 1977
Micrococcus luteus produced a diffusible, esterase inhibitory factor (EIF) which inhibited the activity of cutaneous diphtheroid esterases on Tween 80–CaCl2 agar media. Esterases of Staphylococcus, Micrococcus, Bacillus, and Serratia were not susceptible. EIF did not appear to combine with the substrate or to prevent enzyme synthesis; it was unable to

Mechanism of action of Micrococcus luteus .gamma.-endonuclease

Biochemistry, 1987
Micrococcus luteus extracts contain gamma-endonuclease, a Mg2+-independent endonuclease that cleaves gamma-irradiated DNA. This enzyme has been purified approximately 1000-fold, and the purified enzyme was used to study its substrate specificity and mechanism of action. gamma-Endonuclease cleaves DNA containing either thymine glycols, urea residues, or

On resuscitation from the dormant state of Micrococcus luteus

Antonie van Leeuwenhoek, 1998
It has been found previously that a significant number of Micrococcus luteus cells starved in a prolonged stationary phase (up to 2 months) and then held on the bench at room temperature without agitation for periods of up to a further 2-7 months can be resuscitated in liquid media which contained (statistically) no initially-viable (colony-forming ...

BASE-EXCISION REPAIR IN MICROCOCCUS LUTEUS

1978
ABSTRACT Base-excision repair of DNA damaged by chemicals relies upon the sequential action of specific DNA-glycosylases wich excises the modified bases yielding an apurinic or apyrimidinic site. This site is in turn recognised by a specific endonuclease wich hydrolyse the phosphodiester bond of DNA adjacent to this site.

Postreplication DNA repair in ultraviolet-irradiated Micrococcus luteus

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1975
Postreplication DNA repair was studies in three strains of Micrococcus luteus having different sensitivity to ultraviolet light: a wild type ATCC 5698, a ultraviolet-sensitive mutant G7, deficient in the incision step of repair and in ultraviolet-resistant transformant obtained from G7 by treatment with DNA of wild type cells, Trf(G7). It is shown that

Gamma Endonuclease of Micrococcus luteus: Action on Irradiated DNA

Radiation Research, 1988
Gamma endonuclease is a Mg2+-independent enzyme of Micrococcus luteus that recognizes and cleaves DNA at a variety of altered pyrimidines produced by ionizing radiation. The production of enzyme-recognizable sites (ERS) by ionizing radiation under different irradiation conditions was measured. Ionizing radiation produced the greatest number of ERS when
