the protein subunit Ph1496p elevates the optimum temperature from 55°C (for reconstituted enzyme particles composed of RNase P RNA and four proteins: Ph1481p, Ph1601p, Ph1771p, and Ph1877p) to 70°C which is the temperature optimum of the authentic RNase P from pyrococcus horikoshii AT3

-
The temperature optimum for the reaction is 77 °C, reflecting the thermophilic character of the organism
