Characterization of Three L-Asparaginases from Maritime Pine (Pinus pinaster Ait.)
Frontiers in Plant Science, 2017 Asparaginases (ASPG, EC 3.5.1.1) catalyze the hydrolysis of the amide group of L-asparagine producing L-aspartate and ammonium. Three ASPG, PpASPG1, PpASPG2, and PpASPG3, have been identified in the transcriptome of maritime pine (Pinus pinaster Ait ...

Asparagine Synthetase in Cancer: Beyond Acute Lymphoblastic Leukemia
Frontiers in Oncology, 2020 Asparagine Synthetase (ASNS) catalyzes the synthesis of the non-essential amino acid asparagine (Asn) from aspartate (Asp) and glutamine (Gln). ASNS expression is highly regulated at the transcriptional level, being induced by both the Amino Acid ...

Reducing the Risk of Acrylamide and Other Processing Contaminant Formation in Wheat Products
Foods, 2023 Wheat is a staple crop, consumed worldwide as a major source of starch and protein. Global intake of wheat has increased in recent years, and overall, wheat is considered to be a healthy food, particularly when products are made from whole grains ...

Glutamine Phosphoribosylpyrophosphate Amidotransferase-independent Phosphoribosyl Amine Synthesis from Ribose 5-Phosphate and Glutamine or Asparagine [PDF]
, 2007 Phosphoribosylamine (PRA) is the first intermediate in the common pathway to purines and thiamine and is generated in bacteria by glutamine phosphoribosylpyrophosphate (PRPP) amidotransferase (EC 2.4.2.14) from PRPP and glutamine.

Synthesis and Activation of Asparagine in Asparagine Auxotrophs of Saccharomyces cerevisiae [PDF]
European Journal of Biochemistry, 1979 l‐Asparagine synthesis in Saccharomyces cerevisiae is performed by a glutamine‐dependent asparagine synthetase of the type found in higher organisms.Auxotrophy for asparagine has been obtained in two classes of mutants. In class I, asparagine synthetase activity is cancelled. These mutants combinetwo mutations, asnA− and asnB−. Neither asnA− nor asnB−

Plasma Amino Acids in Horses Suffering from Pituitary Pars Intermedia Dysfunction
Animals, 2022 Pituitary pars intermedia dysfunction is one of the most common diseases of aged horses and ponies. In Parkinson’s disease, which is, similar to PPID, a disease that involves oxidative damage to dopaminergic pathways but with different clinical signs ...

Cereal asparagine synthetase genes [PDF]
Annals of Applied Biology, 2020 AbstractAsparagine synthetase catalyses the transfer of an amino group from glutamine to aspartate to form glutamate and asparagine. The accumulation of free (nonprotein) asparagine in crops has implications for food safety because free asparagine is the precursor for acrylamide, a carcinogenic contaminant that forms during high‐temperature cooking and
