Multiple forms of lactate dehydrogenase in Staphylococcus aureus.
Activities for nicotinamide adenine dinucleotide (NAD)-dependent and NAD-independent forms of lactate dehydrogenase (LDH) were measured in cell-free extracts of Staphylococcus aureus strain PS 6 for the d and l isomers of lactate. Data obtained for the NAD-dependent lactate dehydrogenases indicate that oxidation of both isomers of lactate is due to both an l-lactate-specific LDH and a lactate r...
متن کاملRegulation of Staphylococcus aureus lactate dehydrogenase.
The effect of growth conditions on the specific activity of nicotinamide adenine dinucleotide (NAD)-linked lactate dehydrogenase (LDH) in extracts of Staphylococcus aureus strain SG 511A was examined. Kinetic and electrophoretic experiments, with extracts prepared from aerobically and anaerobically grown cells, provided evidence for only one physiologically significant enzyme. The aerobic level...
متن کاملLactate dehydrogenase activity in certain strains of Staphylococcus aureus.
Lactate dehydrogenase (LDH) was studied in phage-propagating strains 29, 3A, 6, 81, and 42D of Staphylococcus aureus selected from the five groups in the International-Blair series. Cells were cultivated in Brain Heart Infusion (Difco) under nearly anaerobic conditions and were harvested near the end of the log phase. LDH activity was maximal at the end of the exponential growth period and was ...
متن کاملCcpA-Independent Glucose Regulation of Lactate Dehydrogenase 1 in Staphylococcus aureus
Lactate Dehydrogenase 1 (Ldh1) is a key enzyme involved in Staphylococcus aureus NO·-resistance. Full ldh1-induction requires the presence of glucose, and mutants lacking the Carbon-Catabolite Protein (CcpA) exhibit decreased ldh1 transcription and diminished Ldh1 activity. The redox-regulator Rex represses ldh1 directly by binding to Rex-sites within the ldh1 promoter (P(ldh1)). In the absence...
متن کاملInactivation of vancomycin-induced unstable L-forms of Staphylococcus aureus by horse serum
Substitution at codon Ser315 of katG gene, a reliable marker for isoniazid (INH) resistance and proliferate in spite of the loss of cell wall is called an L- form. Unstable L- forms can convert to normal cells but stble L-forms can not.cell wall - deffective state may be induced spontaneously or through the action of an appropriate agent such as antibiotic interfering with the synthesis of cel...
