XXI. Modification of Histidine Residues in Ribonuclease T1 with Iodoacetamide1 ... 1. When ribonuclease T1 (EC 3.1.4.8 [EC]) (0.125% solution) was treated with a 760-fold molar excess of iodoacetamide at pH 8.0 and 37°, about 90% of the original activity was lost in 24 hr. The half-life of the activity was about 8 hr.

In the presence of histidine, ... These residues are also in the disallowed region in the pH 4.8 structure and this suggests they are truly strained in the folding of the protein.6 The overall fold of the pH 8 protein strongly resembles that of the pH 4.8, active, model.6 The rms deviation among all visible Cas is 0.9 A.
