A uridine diphosphoacetylmuramyl hexapeptide from penicillin-treated Streptococcus faecalis.
Uridine diphosphoacetylmuramyl peptide compounds were first isolated from penicillin-treated Staphylococcus aureus, in which they accumulate (1). The major compound that accumulates in this circumstance contains five amino acids and is represented as UDP-Glu’.lc-lactyl-L-Ala-n-Glu-L-Lys-o-;llan-Ala1 (l-3). This compound is believed to be a precursor of the cell wall, which contains, among other...
متن کاملMembrane Adenosine Triphosphatase from Streptococcus faecalis
The membrane adenosine triphosphatase from SfrepfoCOCCUS faecalis has been purified by heat treatment, gel filtration through Agarose, and repeated chromatography on diethylaminoethyl cellulose. The purified ATPase appears to be homogeneous as judged from gel electrophoresis and sedimentation velocity studies. Sedimentation equilibrium studies, which are presented in the succeeding paper, also ...
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...
متن کاملPenicillin-resistant Streptococcus Pneumoniae
Streptococcus pneumoniae is a major cause of pneumonia, meningitis, septicemia, acute otitis media, and other serious infections, severely affecting infants, young children, and the elderly. In the past, S. pneumoniae was uniformly susceptible to penicillin, which remained the drug of choice for serious infections. However, since the mid-1960s, resistance to penicillin, which was first reported...
