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...
متن کاملPyruvate kinase of Streptococcus lactis.
The kinetic properties of pyruvate kinase (ATP:pyruvate-phosphotransferase, EC 2.7.1.40) from Streptococcus lactis have been investigated. Positive homotropic kinetics were observed with phosphoenolpyruvate and adenosine 5'-diphosphate, resulting in a sigmoid relationship between reaction velocity and substrate concentrations. This relationship was abolished with an excess of the heterotropic e...
متن کاملExtracellular Proteinase of Streptococcus Lactis.
Williamson, W. T. (North Carolina State of the University of North Carolina, Raleigh), S. B. Tove, and M. L. Speck. Extracellular proteinase of Streptococcus lactis. J. Bacteriol. 87:49-53. 1964.-Streptococcus lactis was shown to produce an extracellular proteolytic enzyme(s). A 120-fold purification of the proteinase was obtained from the cell-free culture medium by ammonium sulfate fractionat...
متن کاملFactors affecting the initiation of respiration of Streptococcus lactis.
Streptococcus lactis is probably the most important organism used by the dairy industry. However, an examination of the literature indicates that this organism is incapable of many metabolic activities performed by other species of the genus Streptococcus. The report of Farrell (1935) reports a characteristic of many of the streptococci. He used the reduction of indigotetrasulphonate in Thunber...
متن کاملIsolation of a Recombination-Deficient Mutant of Streptococcus lactis ML3t
A recombination-deficient mutant of Streptococcus lactis ML3 designated MMS36 was isolated on the basis of its sensitivity to methyl methanesulfonate. This mutant also displayed sensitivity to UV irradiation. The inability of MMS36 to mediate homologous recombination was demonstrated by transduction of plasmid-linked lactose fermenting ability but not chromosomally mediated streptomycin resista...
