Kinetic constants of recombinant Arabidopsis SSADH1 compared with SSADH from other organisms

Kinetic Constant Arabidopsis Pig Barley Potato
μm
K0.5, SSA 15  ± 5 11 15.9 4.6
Km, NAD+ 130  ± 77 310 166.0 31.0
Ki, NADH 122  ± 86 310
K0.5, GA 500

The kinetic constants are compared to those published for pig SSADH (Blaner and Churchich, 1980), barley SSADH (Yamaura et al., 1988), and potato SSADH (Satya Narayan and Nair, 1989).
