The amino acid sequence of poly ( A )-specific ribonuclease shows homology to the RNase D family of 3'- exonucleases.

This cyclodextrin catalytic system mimics ribonuclease A by its use of a neutral imidazole and an imidazolium cation to selective cleave cyclic phosphate substrates.
33.
Bovine pancreatic ribonuclease became a common model system in the study of proteins largely because it was extremely stable and could be purified in large quantities.
34.
The computer image shows superimposed structures of ribonuclease S and A, with the S-peptide in gold and the active site histidines in hot pink.
35.
In animals, poly ( A ) ribonuclease ( PARN ) can bind to the 5'cap and remove nucleotides from the poly ( A ) tail.
36.
In 1959 Moore and Stein announced the first determination of the complete amino acid sequence of an enzyme, ribonuclease, work which was cited in the Nobel award.
37.
Human angiogenin diverged from ribonuclease, for example, and while the two paralogs remain similar in tertiary structure, their functions within the cell are now quite different.
38.
When the probe is a DNA molecule, S1 nuclease is used; when the probe is RNA, any single-strand-specific ribonuclease can be used.
39.
Mammalian cells are protected from these effects due to their extremely high affinity for ribonuclease inhibitor ( RI ), which protects cellular RNA from degradation by pancreatic ribonucleases.
40.
Its function is to inhibit the ribonuclease activity of its binding partner barnase, with which it forms an extraordinarily tightly bound complex within the cell until barnase is secreted.
