Table 1. Enzymatic kinetics of RNase P with various substrates.

Substrates	K_m, μM	k_cat, min^-1	k_cat/K_m, min^-1·μM^-1
205w	0.42	14	33
90w	0.25	29	116
125w	6.8	31	4.6
145w	11	2.1	0.19
154w	0.54	8.6	16
82c	13	2.2	0.17
ptRNA^Tyr	0.033	29	879
p.4.5S RNA	0.055	56	1,006

These results represent an experiment in which the enzyme parameters for new substrates were measured together. Data for pTyr and p4.5S RNA are published in ref. 3.
