Ribonuclease P All living things synthesize an enzyme - called Ribonuclease P - that cleaves the head (5') end of the precursors of transfer RNA (tRNA) molecules. In bacteria, ribonuclease P is a heterodimer containing ... Full article >>>
For example, ribonuclease inhibitor binds to ribonuclease A with a roughly 20 fM dissociation constant. Other proteins have evolved to bind specifically to unusual moieties on another protein, e.g. Full article >>>
Tandem mass spectrometry (MS-MS and MS-MS-MS) of a crosslinked peptide pair from bovine ribonuclease A shows a fragmentation pattern that allows confirmation of the identities of the two crosslinked peptides. Full article >>>
