5.3.3.2	E116Q	the ratio of maximal velocity to turnover number is 0.09%% of that of the wild-type enzyme	650979	
5.3.3.2	E13R/R235E	the mutant and the wild-type enzyme show similar Vmax values, while the Km of E13R/R235E is smaller than that of the wild type. The mutant is in the tetrameric state even at a concentration where the wild-type enzyme dominantly forms an octamer	719740
