TrxR source kcat (s−1) Km (μm)
kcat/Km (M−1 s−1)
NADPH Trx1 Trx1 NADPH
H. pyloria 75 6.1 22.6 3.3 × 106 1.2 × 107
E. colib 33.5 2.7 3.7 9.1 × 106 1.2 × 107

These values were obtained from the slopes and intercepts of the plots in Fig. 3B at 25°C. 

b

These values were obtained from Lennon and Williams (41).
