NTP Kd(uM) Factor* kpol(sec-1) Factor*
ATP 1.2 (± 0.74) × 102   74 (± 22)  
UTP-untrapped** 1.7 (± 0.53) × 105   0.14 (± 0.052)  
UTP-heparin trap*** 5.3 (± 3.0) × 104 -3.2 0.032 (± 0.02) -4.4
UTP-cold trap*** 5.3 (± 0.065) × 104 -3.2 0.027 (± 4.3 × 10-4) -5.2
  1. *Factor by which data with trap differ from data without trap.
  2. **Only 12 mers were analyzed (because no 11 mers were visible). Data over 500 nM were disregarded.
  3. ***All data.
