Glutamate Pyruvate

α,β,β-Trideutero-L-glutamic acid has been synthesized by incubating L- glutamic acid in D2O at pD 7.8 in the presence of pig-heart glutamate- oxaloacetate aminotransferase and catalytic amounts of pyridoxal 5?- phosphate and oxaloacetic acid. However, when L-glutamic acid is incubated under similar conditions with pig-heart glutamate-pyruvate aminotransferase, in the presence of catalytic amounts of pyridoxal 5?- phosphate and pyruvic acid, α-deutero-L-glutamic acid is obtained.

Resting cell and cell-free extract experiments demonstrated the presence of citritase, oxaloacetic acid decarboxylase, α-acetolactic acid decarboxylase, and pyruvic acid decarboxylase in Streptococcus diacelilactis. Results indicated that citric acid or pyruvic acid was converted to diacetyl and acetylmethylcarbinol with intermediate synthesis of α-acetolactic acid. Acetylmethylcarbinol also was synthesized by condensation of active and free acetaldehyde. Evidence was obtained for the presence of diacetyl reductase and a reversible 2,3-butanediol dehydrogenase in cell-free extracts of S. diacetilactis. The data suggested that S. diacetilactis produced diacetyl from citrate with the intermediate production of oxaloacetate, pyruvate, and α-acetolactate in that order.

SummaryReports on platelet aggregation after addition of calcium or magnesium to EDTA- PRP or platelet suspensions were confirmed. An aggregating principle was found in the EDTA-plasma and the supernatant of the platelet suspensions. Aggregation by magnesium in a platelet suspension was inhibited by adenosine and phosphoenol- pyruvic acid and pyruvate kinase, which suggested that the active principle was identical with ADP. Degradation of ADP in EDTA plasma was blocked.It thus appears that aggregation induced by calcium or magnesium in EDTA-PRP and platelet suspension was due to accumulation of spontaneously liberated ADP, which was not degraded.
