ALDONIC ACID METABOLISM I. Streptococcus faecalis

Hydroxylysine metabolism in Streptococcus faecalis.

Anaerobic Endogenous Metabolism in Streptococcus Faecalis.

Walker, D. J. (CSIRO, University of Adelaide, Adelaide, South Australia), and W. W. Forrest. Endogenous metabolism in Streptococcus faecalis. J. Bacteriol. 87:256-262. 1964.-Washed suspensions of Streptococcus faecalis incubated in phosphate buffer (pH 6.0) under anaerobic conditions released amino acids into the suspending medium. Little or no carbohydrate was released in soluble form, and no ...

Metabolism of resistant mutants of Streptococcus faecalis. I. Isolation and characterization of the mutants.

The currently unavoidable phenomenon of the appearance of drug-refractory leukemic cells in children whose disease was at one time responsive to that drug has served as a stimulus for the study of strains of microorganisms resistant to such agents. A series of mutants of Streptococcusfaecalis has been selected, and these mutants exhibit vari ous degrees of resistance to A-methopterin, 6-mercapt...

Effect of pyrimethamine on folic acid metabolism in Streptococcus faecalis and Escherichia coli.

Pyrimethamine (Daraprim (Burroughs Wellcome) ; 2,4diamino-5-p-chlorophenyl-6-ethylpyrimidine) is used in the treatment and prevention of malaria (1). When used in combination with one of the sulfonamides, it is also effective in the treatment of toxoplasmosis (2) and coccidiosis (3). Pyrimethamine is one of a series of 2,4-diaminopyrimidines which have been shown to be antagonists of folic acid...

The biosynthesis of thymidylic acid. I. Preliminary studies with extracts of Streptococcus faecalis R.

The biosynthesis of deoxythymidine phosphate from deoxyuridine phosphate has been reported to occur in preparations from animal tissues (l-3) and from Escherichia coli (4). In E. co& the reaction occurs much more rapidly after infection of the cells with bacteriophage (5, 6). In the present paper, it has been demonstrated that Streptococcus faecalis R is also a convenient source of thymidylate ...
