WebbWhile the apo and the N3-bound systems favored N δ (HD) and N ϵ (HE) protonation of His41 and His164, respectively, the α-ketoamide was not stably bound in this state. Our results illustrate the importance of using appropriate histidine protonation states to accurately model the structure and dynamics of SARS-CoV-2 M pro in both the apo and … WebbBasic amino acids have really high pKa values (>>7) so they are protonated at pH of 7 or 7.4, with a charge of +1. But Histidine is weird: The pKa for Histidine is really low at 6, so at pH 7 it should be deprotonated leaving a -1 charge. What about the isoelectric point (pI)?
