Micrococcus luteus

Only the major components 119 and 120 exhibited activity against Micrococcus luteus, implying that the aziridine ring is required for antibiotic activity. Madur-...

C. Oligo- and Poly-nucleotides.—The stepwise enzymatic synthesis of internucleotide bonds has been reviewed. A number of polynucleotides containing modified bases have been synthesised " in the past year from nucleoside triphosphates with the aid of a polymerase enzyme, and the enzymatic synthesis of oligodeoxyribonucleotides using terminal deoxynucleotidyl transferase has been studied. Primer-independent polynucleotide phosphorylase from Micrococcus luteus has been attached to cellulose after the latter has been activated with cyanogen bromide. The preparation of insolubilized enzyme has enabled large quantities of synthetic polynucleotides to be made. The soluble enzyme has been used to prepare various modified polycytidylic acids. ...

Here, we discuss a solid-state 19F-NMR approach that has been developed for structural studies of MAPs in lipid bilayers, and how this can be translated to measurements in native biomembranes. We review the essentials of the methodology and discuss key objectives in the practice of 19F-labelling of peptides. Furthermore, the preparation of macroscopically oriented biomembranes on solid supports is discussed in the context of other membrane models. Two native biomembrane systems are presented as examples human erythrocyte ghosts as representatives of eukaryotic cell membranes, and protoplasts from Micrococcus luteus as membranes...

Indeed, these results are qualitatively similar to those depicted in Figs. 12 and 13, and it is therefore tempting to ascribe them to the presence, on the bacterial cell walk, of polyanionic environments surrounding the sites where lysozyme cleaves the polysaccharide network. However, the point is that, although several authors have concluded from various experimental observations that the cell walls of bacteria such as Escherichia coli and Micrococcus luteus are predominantly negatively charged (Katerakky et al, 1953 Salton, 1964 Davies et al, 1969), the complexity of the bacterial cell wall architecture means that little is known about the... 

Fig. 15. Inhibition of the lysis of Micrococcus luteus by lysozyme, kiko (ko = activity in the absence of inhibitor) (A, 0), and optical density increase of an M. luteus suspension at 500 nm, both as a function of polyelectrolyte concentration. Poly(Lys), O Poly(Glu), pH 8.5, I = 0.01, lysozyme 0.55 x 10" M. M. luteus 100 mg liter", +20°C. Inset Recording vs time of the optical density increase of an M. luteus suspension on addition of poly(Lys) at 2.5 X 10" M, at +20°C.

The combined synergistic effects of cyclo(Leu-Pro) and cyclo(Phe-Pro) were effective against five vancomycin-resistant enterococci (VRE) strains Enterococcus faecium (K-99-38), E. faecalis (K-99-17), E. faecalis (K-99-258), E. faecium (K-01-312), and E. faecalis (K-01-511) with MIC values of 0.25—1 mgl . It also showed activity against E. coli, Staphylococcus aureus. Micrococcus luteus, Candida albicans, and Cryptococcus neoformans with MIC values of 0.25—0.5 mg 1. This combination also showed mutagenic activity against Salmonella typhimurium TA98 and TAIOO strains in a Salmonella mutation assay. ... 

This enzyme (also known as DNA-(apurmic or apyrimid-inic site) lyase, AP endonuclease class I, E. coli endonuclease III, Phage-T4 UV endonuclease, and Micrococcus luteus UV endonuclease) catalyzes the cleavage of the phosphodiester bond in a lyase-type reaction, not hydro-... 

The alkaloid K-252a (330) (see Scheme 2.85) was examined against several microbes and found to be active against Micrococcus luteus, Micrococcus flavus FDA16, and Corynebacterium bovis 1810 with a MIC of 6.25gg/mL (314).
