Asparagine synthetase (or aspartate-ammonia ligase) is a chiefly cytoplasmic enzyme that generates asparagine from aspartate. [1] This amidation reaction is similar to that promoted by glutamine synthetase. The enzyme is ubiquitous in its distribution in mammalian organs, but basal expression is relatively low in tissues other than the exocrine ...
Asparagine (symbol Asn or N [2]) is an α-amino acid that is used in the biosynthesis of proteins.It contains an α-amino group (which is in the protonated −NH + 3 form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO − form under biological conditions), and a side chain carboxamide, classifying it as a polar (at physiological pH), aliphatic ...
Acrylamide is often formed in the cooking of starchy foods. During heating the amino acid asparagine, naturally present in starchy foods, undergoes a process called the Maillard reaction, which is responsible for giving baked or fried foods their brown color, crust, and toasted flavor. Suspected carcinogens such as acrylamide and some ...
In the asparagine synthetase reaction, ATP is used to activate aspartate, forming β-aspartyl-AMP. Glutamine donates an ammonium group, which reacts with β-aspartyl-AMP to form asparagine and free AMP. The biosynthesis of aspartate and asparagine from oxaloacetate. Two asparagine synthetases are found in bacteria.
Neurosurgeon Dr. Paul Saphier, M.D., shared some ingredients to a healthy breakfast for heart and brain health, including yogurt, fruit and seeds, in a video posted to X.
In enzymology, an aspartate—ammonia ligase (EC 6.3.1.1) is an enzyme that catalyzes the chemical reaction. ATP + L-aspartate + NH 3 AMP + diphosphate + L-asparagine. The 3 substrates of this enzyme are ATP, L-aspartate, and NH 3, whereas its 3 products are AMP, diphosphate, and L-asparagine.
Asparagine synthase (glutamine-hydrolysing) (EC 6.3.5.4, asparagine synthetase (glutamine-hydrolysing), glutamine-dependent asparagine synthetase, asparagine synthetase B, AS, AS-B) is an enzyme with systematic name L-aspartate:L-glutamine amido-ligase (AMP-forming).
