Question

Quizplus · Accepted Answer

Aspartyl transcarbamylase (ATCase) is not a serine protease; it is involved in the pyrimidine biosynthesis pathway and does not utilize a serine residue in its catalytic mechanism, unlike trypsin, chymotrypsin, and thrombin, which are serine proteases characterized by their use of a serine residue in the catalytic site.
