Asp239

Asp239 is a specific amino acid residue found within certain protein structures. Its precise role and significance depend heavily on the protein in which it resides. In the context of protein function, individual amino acid residues like Asp239 can be crucial for catalysis, substrate binding, structural integrity, or interaction with other molecules. The aspartic acid (Asp) at position 239 implies a negatively charged side chain at physiological pH, which can participate in electrostatic interactions or act as a proton donor/acceptor in enzymatic reactions. Mutations or modifications at this position can lead to altered protein activity, stability, or interactions, potentially impacting biological processes. Researchers often investigate the effects of changing Asp239 to other amino acids to understand its contribution to the protein's overall function. The importance of Asp239 is therefore typically discussed in the specific scientific literature pertaining to the protein it is part of, such as in studies of enzyme mechanisms or protein-protein interactions.
