Histidine 192-201 ribonuclease A family member 1, pancreatic Homo sapiens 95-109 19540766-1 2009 Nucleoside-amino acid conjugates have been employed to inhibit the ribonucleolytic activity of ribonuclease A (RNase A) and affect the protonation/deprotonation equilibrium of its active site histidine residues. Histidine 192-201 ribonuclease A family member 1, pancreatic Homo sapiens 111-118 19540766-4 2009 The nucleoside-serine conjugate occupies the active site of RNase A and preferential perturbs the pK(a) value of His-119 by its "free amino group" as found from (1)H NMR studies. Histidine 113-116 ribonuclease A family member 1, pancreatic Homo sapiens 60-67 19540766-5 2009 Docking studies revealed that the free amino groups of the most active compounds are within hydrogen bonding distance of His-119 in inhibitor-RNase A complexes. Histidine 121-124 ribonuclease A family member 1, pancreatic Homo sapiens 142-149
