asparagiiniaminohappotähteeseens
Asparagiiniaminohappotähteeseens refers to the aspartyl residue in a polypeptide chain. Aspartyl is a derivative of the amino acid aspartic acid, where the carboxyl group of the beta-carbon has been deprotonated and formed a peptide bond with another amino acid. Aspartic acid is an acidic amino acid due to the presence of its side chain carboxyl group. When incorporated into a protein, this residue can exist in a neutral or charged state depending on the surrounding pH. At physiological pH, the side chain carboxyl group is typically deprotonated, giving the residue a negative charge. This negative charge plays a significant role in protein structure, function, and interactions with other molecules. Asparagiiniaminohappotähteeseens can participate in hydrogen bonding, ionic interactions, and act as binding sites for metal ions. Its presence can influence the overall folding and stability of a protein, as well as its catalytic activity in enzymes. The specific position and context of an asparaginyl residue within a protein sequence determine its precise contribution to the protein's properties.
