Ribonuclease, RNase A family, 1

RNase A
This gene encodes a member of the pancreatic-type of secretory ribonucleases, a subset of the ribonuclease A superfamily. The encoded endonuclease cleaves internal phosphodiester RNA bonds on the 3'-side of pyrimidine bases. It prefers poly(C) as a substrate and hydrolyzes 2',3'-cyclic nucleotides, with a pH optimum near 8.0. The encoded protein is monomeric and more commonly acts to degrade ds-RNA over ss-RNA. Alternative splicing occurs at this locus and four transcript variants encoding the same protein have been identified. [provided by RefSeq, Jul 2008] (from NCBI)

Perturbation of the Conformational Dynamics of an Active-Site Loop Alters Enzyme Activity.
Doucet et al., Québec, Canada. In Structure, Jan 2016
Using RNase A as a model, we demonstrate that elimination of a single methyl group located >10 Å away from the reaction site significantly alters conformational integrity and binding properties of the enzyme.
Integration of kinetic isotope effect analyses to elucidate ribonuclease mechanism.
York et al., Cleveland, United States. In Biochim Biophys Acta, Nov 2015
The basic features of this mechanism are often cited to explain rate enhancement by both protein and RNA enzymes that catalyze RNA 2'-O-transphosphorylation. Recent kinetic isotope effect analyses and computational studies are providing a more chemically detailed description of the mechanism of RNase A and the rate limiting transition state.

RNase A uses four basic strategies to promote this reaction: geometric constraints, activation of the nucleophile, transition-state stabilization, and leaving group protonation.
