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 ...
Potassium asparaginate is a potassium salt of L-asparagine amino acid. [2] [3] [4] [5]Potassium asparaginate can be considered both a salt and a coordination complex. [6] [3] As a salt, potassium asparaginate is formed when the potassium ion (K +) replaces the hydrogen ion (H +) in the carboxyl group of L-asparagine, an amino acid; in this process, the carboxyl group (–COOH) in L-asparagine ...
In molecular biology, post-translational modification (PTM) is the covalent process of changing proteins following protein biosynthesis. PTMs may involve enzymes or occur spontaneously. Proteins are created by ribosomes , which translate mRNA into polypeptide chains , which may then change to form the mature protein product.
Asparagine is synthesized by an ATP-dependent addition of an amino group onto aspartate; asparagine synthetase catalyzes the addition of nitrogen from glutamine or soluble ammonia to aspartate to yield asparagine. [42] The diaminopimelic acid lysine biosynthetic pathway. The diaminopimelic acid biosynthetic pathway of lysine belongs to the ...
Deamidation is a chemical reaction in which an amide functional group in the side chain of the amino acids asparagine or glutamine is removed or converted to another functional group. Typically, asparagine is converted to aspartic acid or isoaspartic acid. Glutamine is converted to glutamic acid or pyroglutamic acid (5-oxoproline).

3-Hydroxyasparagine also known as β-hydroxyasparagine (beta-hydroxyasparagine) is a modified asparagine amino acid. It appears in posttranslational modification of cbEGF-like domains which can occur in humans and other Eukaryotes. The amino acid code used for this is Hyn. The modified amino acid residue is found in fibrillin-1. [1]
The different types of lipid-linked oligosaccharide (LLO) precursor produced in different organisms.. N-linked glycosylation is the attachment of an oligosaccharide, a carbohydrate consisting of several sugar molecules, sometimes also referred to as glycan, to a nitrogen atom (the amide nitrogen of an asparagine (Asn) residue of a protein), in a process called N-glycosylation, studied in ...
