(a) Common structure of α-amino acids, position of the α-carbon is labeled; ‘R’ represents any number of possible chemical structures, which may be as simple as a single hydrogen atom (–H, as in the amino acid glycine) or more complex chemical groups, as in (b); (b) Examples...
The other is a general acid–base mechanism. According to this mechanism proposed for Ec-RNase HI,22 His-124 activates an H2O molecule that acts as a general base. Asp-134 coordinates the H2O molecule. Glu-48 anchors an H2O molecule that acts as a general acid. Asp-70 governs the ...
Amino acids are the building blocks that make up all proteins, polypeptides and peptides. Each amino acid consists of a central carbon, known as the α-carbon, to which an amino group (-NH2), an acidic carboxyl group (-COOH) and an organic side chain

Structure and Properties of Biologic Molecules Amino acids An amino acid contains four functional groups organized around the α-carbon: the α-amino group, the α-carboxyl group, a unique side chain (hydrogen in glycine), and hydrogen. The asymmetry of the α-carbon gives rise to two opticall...
Protein Structure Prediction 5.1 Protein structural class The concept of “amino acid composition” plays a major role in predicting the structural class of globular proteins, and it is defined as the statistical preference of each of the amino acid residues occurring in protein molecules. The amino...
