Lactofferrin binding to lysozyme-treated Micrococcus luteus

Biochimica et Biophysica Acta (BBA) - General Subjects, 1982
When 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 ...

Structure of cell-wall glycopolymers of Micrococcus luteus C01

Carbohydrate Research, 2021
Glycopolymers of two types were isolated from the cell wall of Micrococcus luteus C01 by stepwise extraction with cold and hot 10% aq CCl3CO2H. The following structures of the glycopolymers were established by compositional analysis and 1D and 2D NMR spectroscopy: where L-Glu indicates glutamic acid.

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

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.

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

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

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.

[25] Nonaprenylpyrophosphate synthetase from Micrococcus luteus

1985
Publisher Summary This chapter describes the isolation of enzyme, the nonaprenylpyrophosphate synthetase from Micrococcus luteus. A nonaprenylpyrophosphate synthetase fraction obtained from Micrococcus luteus catalyzes the condensation of isopentenyl pyrophosphate with geranyl pyrophosphate to yield all-trans-prenyl pyrophosphates ranging in carbon ...

Acetylputrescine deacetylase from Micrococcus luteus K-11

Biochimica et Biophysica Acta (BBA) - General Subjects, 1986
Abstract An acetylputrescine deacetylase was induced in Micrococcus luteus K-11, and was partially purified and characterized briefly. The enzyme was most active toward acetylputrescine, followed by N8-acetylspermidine and acetylcadaverine, but was inactive toward N1-acetylspermidine and N1-acetylspermine.
