Subunits Comment Organism
oligomer RNase P consists of RNase P RNA (PhopRNA) and five protein cofactors designated PhoPop5, PhoRpp21, PhoRpp29, PhoRpp30, and PhoRpp38. PhoPop5 and PhoRpp30 fold into a heterotetramer and cooperate to activate a catalytic domain (C-domain) in PhopRNA, whereas PhoRpp21 and PhoRpp29 form a heterodimer and function together to activate a specificity domain (S-domain) in PhopRNA. PhoRpp38 plays a role in elevation of the optimum temperature of RNase P activity, binding to kink-turn (K-turn) motifs in two stem-loops in PhopRNA Pyrococcus horikoshii
