WebCytomegalovirus protease [b] uses a pair of histidines, one as the base, as usual, and one as the acid. [1] The second histidine is not as effective an acid as the more common aspartate or glutamate, leading to a lower catalytic efficiency. In some enzymes, the acid member of the triad is less necessary and some act only as a dyad.
