Table 3 PsANR reaction kinetics using cyanidin, pelargonidin or delphinidin as a substrate
From: Characterization of proanthocyanidin metabolism in pea (Pisum sativum) seeds
Substrate | Km(μM) | Vmax(nmol mg-1-min-1) | k cat (sec-1) | k cat /Km(M-1-sec-1) |
|---|---|---|---|---|
Pelargonidin | 39.0 ± 0.1a | 72.5 ± 2.2a | 1.2 × 10-3 | 30.7 |
Cyanidin | 37.0 ± 0.2 | 30.2 ± 5.0 | 0.5 × 10-3 | 13.5 |
Delphinidin | 183.6 ± 0.2 | 47.3 ± 6.4 | 0.8 × 10-3 | 4.3 |
