  • Title: Structural changes in ribonuclease P RNA in the hyperthermophilic archaeon Pyrococcus horikoshii OT3 induced on interaction with proteins.
    Author: Kosaka S, Hada K, Nakashima T, Kimura M.
    Journal: Biosci Biotechnol Biochem; 2010; 74(2):394-6. PubMed ID: 20139624.
    Abstract:
    The activated structure of RNase P RNA (PhopRNA) in Pyrococcus horikoshii OT3 was characterized by circular dichroism (CD) and ultraviolet (UV) absorbance spectra. The results suggested that interaction of four RNase P proteins (PhoPop5, PhoRpp21, PhoRpp29, and PhoRpp30) with PhopRNA results in destabilization of base stacking in PhopRNA, whereas the addition of a fifth protein, PhoRpp38, increases base stacking in PhopRNA.
