Question

glycine is a highly conserved amino acids residues in the evolution of protein why give me answer with introduction and structure​

Answer 1

Explanation:

Six glycine residues of human muscle acylphosphatase (AcP) are evolutionarily conserved across the three domains of life. We have generated six variants of AcP, each having a glycine substituted by an alanine (G15A, G19A, G37A, G45A, G53A, and G69A). Three additional variants had Gly45 replaced by serine, glutamate, and arginine, respectively. The mutational variants do not, on average, have a lower conformational stability than other variants with substitutions of nonconserved residues. In addition, only the G15A variant is enzymatically inactive. However, all variants, with the exception of the G15A mutant, form amyloid aggregates more rapidly than the wild-type. Dynamic light-scattering experiments carried out under conditions close to physiological confirm that aggregate formation is generally more pronounced for the glycine-substituted variants.
