... global architecture of all the variant proteins is very similar to that of the parent BS-RNase, and by the close similarity among the X-ray structures of swapped isoforms of hA-BS-RNase and BS-RNase ... the equilibrium mixture is changed from 2 : 1 to 1 : 2 [12]. On the basis of the hypothesis that ascribes the special functions of BS-RNase to the swapped form, in this stu...
