Mimics hypothyroidism difference in the clinical progress of the two sisters is possibly related to a difference in expressivity of the same mutation, with possible presence of hypothyroldism gene modifier. Chymotrypsin catalysis of the hydrolysis of a protein substrate in red is performed in two steps. Hence, the NMR-derived structure may significantly differ from that of a protein in its native state. With ac4C and N 4 -acetylcytosine, the turnover number of the Glu74Ala mutant was found fold and fold lower, respectively, than that of the wild-type enzyme.
