Effect of protein synthesis on plasmid maintenance in Streptococcus faecalis.
Plasmid-to-chromosome ratios in Enterobacteriaceae, upon interruption of protein synthesis by chloramphenicol, are either conserved or increased when measured by dye buoyant density centrifugation. We have found, on the other hand, that the effect of inhibition of protein synthesis on the amount of covalently closed circular deoxyribonucleic acid visualized by this method in two strains of Stre...
متن کاملThe decarboxylation of L-phenylalanine by Streptococcus faecalis R.
Gale (1) and Epps (2) have reported the properties of an enzyme obtained from various strains of Streptococcus faecalis which decarboxylates tyrosine and dihydroxyphenylalanine. Both of these authors reported that the enzyme preparations, whether made by washing the whole organism, by drying the cells with acetone, or by further purification procedures, were specific to the above two amino acid...
متن کاملNovel plasmid-based genetic tools for the study of promoters and terminators in Streptococcus pneumoniae and Enterococcus faecalis.
Promoter-probe and terminator-probe plasmid vectors make possible to rapidly examine whether particular sequences function as promoter or terminator signals in various genetic backgrounds and under diverse environmental stimuli. At present, such plasmid-based genetic tools are very scarce in the Gram-positive pathogenic bacteria Streptococcus pneumoniae and Enterococcus faecalis. Hence, we deve...
متن کاملaureus, and Streptococcus faecalis
SYNOPSIS The incidence of trimethoprim resistance in coliforms and multiresistant strains of Staphylococcus aureus isolated in Bristol from 1970 to 1972 is low-2-3 and 1 0% respectively. The resistance is probably intrinsic; there is no evidence that it is R-factor or plasmid mediated. A single mechanism that confers resistance to both trimethoprim and sulphamethoxazole has not been detected. N...
متن کاملPhospholipids of Streptococcus faecalis.
Autoradiograms of total lipid extracts from Streptococcus faecalis ATCC 9790, harvested in the stationary phase from a medium containing (32)P-orthophosphate, showed six major spots. The corresponding compounds were identified as diphosphatidylglycerol (possibly with a penta acyl structure); phosphatidylglycerol; a provisionally identified mixture of alanylphosphatidylglycerol and of the 2'-lys...
