WebEnzymes are encoded as genes in the DNA — these genes are then transcribed to produce RNA and (for most enzymes§) then translated† to make a protein that has a catalytic … WebEnzymes are subjected to regulation, to adapt to the requirements of different cells. This regulation can occur by changes in S concentration, covalent modifications (phosphorylation), and by allosteric factors that bind to a place in the E different to the active site. Isozymes are different proteins that have the same enzyme activity.
WebEnzymes are encoded as genes in the DNA — these genes are then transcribed to produce RNA and (for most enzymes§) then translated† to make a protein that has a catalytic activity (i.e. is an enzyme).
