CRYSTAL STRUCTURE OF RIBONUCLEASE A (RETRO-SOAKED FORM)CRYSTAL STRUCTURE OF RIBONUCLEASE A (RETRO-SOAKED FORM)
Structural highlights
FunctionRNAS1_BOVIN Endonuclease that catalyzes the cleavage of RNA on the 3' side of pyrimidine nucleotides. Acts on single stranded and double stranded RNA.[1] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedDespite the increasing number of successful determinations of complex protein structures the understanding of their dynamics properties is still rather limited. Using X-ray crystallography, we demonstrate that ribonuclease A (RNase A) undergoes significant domain motions upon ligand binding. In particular, when cytidine 2'-monophosphate binds to RNase A, the structure of the enzyme becomes more compact. Interestingly, our data also show that these structural alterations are fully reversible in the crystal state. These findings provide structural bases for the dynamic behavior of RNase A in the binding of the substrate shown by Petsko and coworkers (Rasmussen et al. Nature 1992;357:423-424). These subtle domain motions may assume functional relevance for more complex system and may play a significant role in the cooperativity of oligomeric enzymes. Reversible substrate-induced domain motions in ribonuclease A.,Vitagliano L, Merlino A, Zagari A, Mazzarella L Proteins. 2002 Jan 1;46(1):97-104. PMID:11746706[2] From MEDLINE®/PubMed®, a database of the U.S. National Library of Medicine. See AlsoReferences
