Haematin-dependent Oxidative Phosphorylation in Streptococcus faecalis

Diacetyl oxidation by Streptococcus faecalis, a lipoic acid dependent reaction.

In the over-all reaction, one molecule of diacetyl is oxidized to two molecules of acetate, and another molecule of diacetyl is reduced to acetoin. The reaction was shown to require cocarboxylase (DPT).2 Subsequently, Schweet et al. (1951) expanded this finding and pointed out the similarity between the diacetyl reaction and pyruvic acid oxidation, with respect to the metabolism of the "active ...

Hydroxylysine metabolism in Streptococcus faecalis.

aureus, 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...

Phospholipids 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...
