BASE-EXCISION REPAIR IN MICROCOCCUS LUTEUS
1978ABSTRACT 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.

Conversion of o-succinylbenzoate to dihydroxynaphthoate by extracts of Micrococcus luteus
Biochemistry, 1980Cell-free extracts were prepared from either freshly grown or spray-dried cells of Micrococcus luteus ATCC 4698 by treatment with deoxyribonuclease and lysozyme. These extracts converted o-succinylbenzoic acid (OSB) to 1,4-dihydroxy-2-naphthoic acid (DHNA) as shown by spectrophotofluorometric and radioactivity assays.

Gamma Endonuclease of Micrococcus luteus: Action on Irradiated DNA
Radiation Research, 1988Gamma 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

Postreplication DNA repair in ultraviolet-irradiated Micrococcus luteus
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1975Postreplication 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

Micrococcus luteus pneumonia: A case report and review of the literature
Medical and Pediatric Oncology, 1979AbstractThe clinical course of a 69‐year‐old male with acute myelogenous leukemia is described who, while extremely leukopenic (<100 neutrophils/μ1) from chemotherapy, developed a cavitating pneumonia due to a gram‐positive coccus, Micrococcus luteus. Aggressive antibiotic management and attainment of complete remission of his leukemia resulted in a

Stimulation of the multiplication of Micrococcus luteus by an autocrine growth factor
Archives of Microbiology, 1999Viable cells of Micrococcus luteus secrete a proteineous growth factor (Rpf) which promotes the resuscitation of dormant, nongrowing cells to yield normal, colony-forming bacteria. When washed M. luteus cells were used as an inoculum, there was a pronounced influence of Rpf on the true lag phase and cell growth on lactate minimal medium. In the absence

Competitive biosorption of thorium and uranium by Micrococcus luteus
Journal of Radioanalytical and Nuclear Chemistry, 2004Eighteen species of bacteria were screened for abilities to adsorb thorium and uranium. High adsorbtion capacity was observed for thorium by Arthrobacter nicotianae and Micrococcus luteus, and for uranium by Arthrobacter nicotianae. The adsorption of both thorium and uranium by Micrococcus luteus cells was rapid, was affected by the solution pH, and ...

Journal of Molecular Biology, 1971
Abstract Micrococcus luteus DNA polymerase, which can be activated by either Mn 2+ or Mg 2+ , responds differently to the presence of these two cations with M. luteus DNA (72% G + C) or poly (dG · dC), while with DNA's or polymers of high A + T content, no differences are observed. With M.

Micrococcus luteus endocarditis: Case report and review of the literature
Zentralblatt für Bakteriologie, 1995This paper includes a report on a case of prosthetic valve endocarditis due to Micrococcus luteus and a review of the sixteen cases of endocarditis due to Micrococcus species reported in the literature. The patient was successfully treated with rifampicin combined for two weeks with gentamicin and vancomycin and for another four weeks with teicoplanin.

[5] The purification of the DNA polymerase from Micrococcus luteus
1974Publisher Summary A DNA polymerase has been purified from Micrococcus luteus . It catalyzes the incorporation of deoxyribonucleotides into natural and synthetic polynucleotides containing 3’-hydroxyl priming sites in the presence of Mg 2+ or Mn 2+ ions.
