Mutating Cysteine to Alanine instead of Serine. Why?

WebHowever, alteration to aspartate, glutamate, and glutamine blocked passage of water, glycerol, and other organic solutes. While LmAQP1 is a mercurial insensitive water channel, mutation of the adjacent threonine (Thr164) to cysteine led to inhibition of water passage by Hg 2+. This inhibition could be reversed upon addition of β-mercaptoethanol. WebCysteine is a sulfur-containing amino acid that is synthesized from methionine (see Fig. 103.3 ). Oxidation of cysteine forms cystine, a poorly soluble dimer. The most common … 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. cse 120 final exam
