All … WebFeb 1, 2007 · The cysteine (or serine) at the N-terminus of the intein, when mutated to alanine, eliminates N-terminal cleavage activity, and therefore also inhibits splicing (Fig. 1, right). With this mutation, C-terminal cleavage is isolated, and the peptide bond between the C-terminal of the intein (asparagine) and the N-terminal of the C-extein is cleaved.

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. WebJul 15, 2024 · The C-terminal domain of VP40 contains two highly-conserved cysteine residues at positions 311 and 314, but their role in the viral life cycle is unknown. We therefore investigated the properties of VP40 mutants in which the conserved cysteine residues were replaced with alanine.

Alanine Scanning was used to determine simultaneously the functional contributions of 19 side chains buried at the interface between human growth hormone and the extracellular domain of its receptor. Each amino acid in the side chains was substituted by alanine.
