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.
