The structures of the amino acids leucine and isoleucine are shown:




If a mutation in the DNA of a globular enzyme changed all of the leucine amino acids to isoleucine, predict how the relative position of the amino acid in the tertiary structure of the protein would be affected when the protein is placed in an aqueous solution. If the leucine amino acids were found within the active site of the enzyme, discuss the effect this change is likely to have on enzymatic function.

Christian Anfinsen investigated the structure of bovine pancreatic ribonuclease A in 1950s, and discovered that the amino acid sequence of a protein determines its native conformation and the conformation determines its biological activity. In his experiment, he denatured bovine pancreatic ribonuclease A in an aqueous solution containing the denaturant urea, and the reducing reagent b-mercaptoethanol. The denatured enzyme completely lost its enzymatic activity. On exposure to air after removal of the denaturant and b-mercaptoethanol, the ribonuclease spontaneously reoxidised and regained...

Decide the sentences are True or False, and show as T or F The basis of precipitation of proteins by ammonium sulfate is described by ammonium sulfate binds water molecules, making them less available for hydration of proteins. The most efficient substrate of an enzyme is usually considered to be the substrate with the largest kcat/Km. Peripheral membrane proteins behave like typical soluble proteins when released from membranes. An integral membrane protein will commonly be solubilized by extraction with a...
