Electrodiffusion of ethidium cation into Micrococcus luteus cells
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1994Ethidium 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.

Lactofferrin binding to lysozyme-treated Micrococcus luteus
Biochimica et Biophysica Acta (BBA) - General Subjects, 1982When the cell lysis of Micrococcus luteus by hen egg white or human lysozyme is performed in the presence of bovine or human lactoferrin, a temporary increase of the turbidity of the solution as followed at 450 nm is observed. Examination of the suspension under light microscopy has proven that the protoplasts produced upon lysozyme action are ...

On resuscitation from the dormant state of Micrococcus luteus.
Antonie van Leeuwenhoek, 1998It 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
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

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

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

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.
