Sinorhizobium meliloti 1021 and Rhizobium etli CE3 turn over nitrogen and carbon from glutamine to ammonium and CO2, respectively. Some of the ammonium released is assimilated back into glutamine, indicating that a glutamine cycle similar to that in

Certain halogenated hydrocarbons, e.g., dichloroacetylene, are nephrotoxic to experimental animals and neurotoxic to humans; cysteine-S-conjugate beta-lyases may play a role in the nephrotoxicity. We now show that with dichlorovinylcysteine as substr

L-[13N]Tyrosine and L-[13N]phenylalanine were synthesized using immobilized enzymes by two methods. In method 1, [13N]ammonia is converted to L-[13N]glutamate; transamination with p-hydroxyphenylpyruvate yields L-[13N]tyrosine. [13N]Tyrosine is separ

Eleven patients with untreated primary Ewing sarcoma were studied with intravenously administered 13N-labeled L-glutamate. Seven were repeatedly scanned during chemotherapy using this agent and 99mTc-methylene diphosphonate (99mTc-MDP). The untreated

An investigation was performed to correlate the regional uptake of N-13 L-glutamate with histologic changes in tumor tissue in patients undergoing adjuvant chemotherapy for osteogenic sarcoma. A parametric image was produced by calculating the ratio

NH2OH was labeled with a β+emitter (13N, t1/2 = 9 96 min.). Hydroxyl[13N]amine was synthesized from HSO and [13N]nitrite (produced via the 160(p,α)13N reaction by proton bombardment of H2O). The synthesis reactions are: Hydroxyl[13N]amine was purif
