Acetylation is a post-translational modification that is used in the regulation of enzymes. An acetyl group is usually added to a lysine side chain in an enzyme (see the picture). Choose the best explanation for how this process affects the enzyme. WHN, NH₂ O 'Om WHN. Om gla 0- NH A) The acetyl group changes the charge on the side chain from a positive charge to neutral. This causes a change in conformation which affects the activity of the enzyme. B) The acetyl group changes the charge on the side chain from neutral to a positive charge. This causes a change in conformation which affects the activity of the enzyme. C) The acetyl group is a cofactor that binds tightly to the enzyme through intermolecular forces. This cofactor activates the enzyme. D) The acetyl group binds two side chains. together closing the active site which affects the activity of the enzyme.
