Cytidine 2′,3′-cyclic monophosphate (2′,3′-CyclicCMP) (2′,3′-cCMP) is used as a model substrate for kinetic analysis of various ribonucleases, especially ribonuclease A.
Although highly stable toward unfolding, native ribonuclease A is known to be cleaved by unspecific proteases in the flexible loop region near Ala20. With the aim to create a protease-resistant ribonuclease A, Ala20 was substituted for Pro by site-directed mutagenesis.

Human pancreatic ribonuclease (HP-RNase) has considerable promise as a therapeutic agent. Structure-function analyses of HP-RNase have been impeded by the difficulty of obtaining the enzyme from its host. Here, a gene encoding HP-RNase was designed, synthesized, and inserted into two
Isothermal titration calorimetry (ITC) and progress curve analysis was used to measure the enzyme kinetic parameters (KM and kcat) of the hydrolysis of cCMP by RNase-A, a reaction that includes end-product competitive inhibition by 3'-CMP. The heat generated from injection

The study of the temperature dependence of the hydrolysis of cytidine 2',3'-phosphate by bovine pancreatic ribonuclease A (EC 3.1.27.5) at pH 7.0 by using the pH-stat method showed a transition at 4 degrees C [J. A. Biosca and C. M.

Protein nitration can occur as a result of peroxynitrite-mediated oxidative stress. Excess production of peroxynitrite (PN) within the cellular medium can cause oxidative damage to biomolecules. The in vitro nitration of Ribonuclease A (RNase A) results in nitrotyrosine (NT) formation
