Glutamine (Gln or Q) ((2S)-2-amino-4-carbamoyl-butanoic acid) is a polar, uncharged amino acid with the formula HOOCCH(NH2)(CH2)2CONH2. The abbreviation Glx or Z represents either Gln or Glu. The side chain contains an amide group in place of the carboxylate and can be considered ...

Amino acids play a central role in cellularmetabolism, and organisms need to synthesize most of them (Figure 1). Many of us become familiar with amino acids when we first learn abouttranslation, the synthesis ofproteinfrom thenucleic acidcode inmRNA. To date, scientists have discovered more tha...
Hence, glycyl-tRNA synthetase (GlyRS) can only form interactions with the backbone atoms of the ligand. Furthermore, asparaginyl-tRNA synthetases (AsnRSs) mediate highly conserved hydrogen bonds with the amide group of their asparagine ligand. The non-standard amino acid pyrrolysine is bound by ...
Amino Acid Derivative In subject area: Pharmacology, Toxicology and Pharmaceutical Science An amino acid analogue results from the substitution of the α-amino group of an amino acid with a non-nitrogenous group. From: Encyclopedia of Dairy Sciences (Second Edition), 2011 About this pageSet ale...
Peptides When the amino group of one amino acid reacts with the carboxyl group of another amino acid, a peptide bond is formed and a molecule of water is released. This can bond joins amino acids together to form proteins The peptide bond is slightly shorter than otter single c-n bonds....
but only a subset of amino acids is involved in nonessential amino acid (NEAA) synthesis (e.g., glutamine, glutamate, methionine, and phenylalanine). Among the amino acids involved in NEAA synthesis, glutamine supplies nitrogen for synthesizing the amide group of asparagine. It also contributes ...
transfer an amino group from the α-carbon of anamino acidamino acid to the α-carbon of an oxo acid, producing a new amino acid and a new oxo acid. A simplified representation of the main amino acidbiosynthesispathways in plants is presented inFig. 1. In addition, aromatic aminotransferase...
