  2. Asparagine - Wikipedia

    en.wikipedia.org/wiki/Asparagine

    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 ...

  3. Asparaginase - Wikipedia

    en.wikipedia.org/wiki/Asparaginase

    Asparaginase is an enzyme that is used as a medication and in food manufacturing. [6] [7] As a medication, L-asparaginase is used to treat acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL). [6] It is given by injection into a vein, or muscle. [6] A pegylated version is also available. [8] In food manufacturing it is used to ...

  4. Essential amino acid - Wikipedia

    en.wikipedia.org/wiki/Essential_amino_acid

    These six are alanine, aspartic acid, asparagine, glutamic acid, serine, [2] and selenocysteine (considered the 21st amino acid). Pyrrolysine (considered the 22nd amino acid), [3] which is proteinogenic only in certain microorganisms, is not used by and therefore non-essential for most organisms, including humans.

  5. Asparagine synthetase - Wikipedia

    en.wikipedia.org/wiki/Asparagine_synthetase

    Escherichia coli derived asparagine synthetase is a dimeric protein with each subunit folding into two distinct domains. [4] The N-terminal region consists of two layers of six-stranded antiparallel β-sheets between which is the active site responsible for the hydrolysis of glutamine. [4]

  6. Amino acid synthesis - Wikipedia

    en.wikipedia.org/wiki/Amino_acid_synthesis

    The enzyme asparagine synthetase produces asparagine, AMP, glutamate, and pyrophosphate from aspartate, glutamine, and ATP. 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.

  7. Asparagus - Wikipedia

    en.wikipedia.org/wiki/Asparagus

    Asparagus has been used as a vegetable owing to its distinct flavor, and in medicine due to its diuretic properties and its purported function as an aphrodisiac. It is pictured as an offering on an Egyptian frieze dating to 3000 BC. In ancient times, it was also known in Syria and in the Iberian Peninsula.

  9. Asx turn - Wikipedia

    en.wikipedia.org/wiki/Asx_turn

    It consists of three amino acid residues (labeled i, i+1 and i+2) in which residue i is an aspartate (Asp) or asparagine (Asn) that forms a hydrogen bond from its sidechain CO group to the mainchain NH group of residue i+2. About 14% of Asx residues present in proteins belong to Asx turns.
