WebbThe isoelectric point (pI) is the pH value at which the molecule carries no electrical charge. The concept is particularly important for zwitterionic molecules such as amino acids, … WebbAmino acid pK a values. pK a values of amino acid side chains play an important role in defining the pH-dependent characteristics of a protein. The pH-dependence of the activity displayed by enzymes and the pH-dependence of protein stability, for example, are properties that are determined by the pK a values of amino acid side chains.. The pK a …
WebbIn the ENR-FLuc system, Phe194 and Phe250 provided a more favorable contribution to the binding, and the indole rings of the two amino acid residues form a face-to-face π-π stacking interaction with the diazohexane ring structure of the ENR antibiotic, thereby increasing the van der Waals forces of binding, which is directly responsible for the … WebbAmino acids are the fundamental building blocks of peptides and proteins. Peptides, which are chains of amino acids, are frequently used as signaling molecules within the body …
