WebAlanine mutagenesis A method of systematic alanine substitution is useful in identification of functional epitopes. This systematic alanine substitution is called as alanine-scanning mutagenesis. The substitution removes all the side chain atoms past the beta-carbon.

Alanine - an overview ScienceDirect Topics
In molecular biology, alanine scanning is a site-directed mutagenesis technique used to determine the contribution of a specific residue to the stability or function of a given protein. Alanine is used because of its non-bulky, chemically inert, methyl functional group that nevertheless mimics the secondary structure preferences that many of the other amino acids possess. Sometimes bulky a… A conservative replacement (also called a conservative mutation or a conservative substitution) is an amino acid replacement in a protein that changes a given amino acid to a different amino acid with similar biochemical properties (e.g. charge, hydrophobicity and size). Conversely, a radical replacement, or radical substitution, is an amino acid replacement that exchanges an initial amino acid by a final amino acid with different physicochemical properties. WebJun 1, 2001 · Proline and serine seem to be more closely related to the polar residues. The weakly polar residue alanine has positive correlation only with the non-polar residues. We propose that mutations between residues with high positive correlation have a high chance of maintaining the thermodynamic stability of the 3D structure. sheldon gives penny chocolate
