Vmax is 2.34 nkat/mg for cinnamic acid, 2.69 nkat/mg for p-coumaric acid, 2.59 nkat/mg for caffeic acie, 1.65 nkat/mg for ferulic acid, 2.24 nkat/mg for 5-hydroxyferulic acid, 1.21 nkat/mg for sinapic acid, 1.08 nkat/mg for benzoic acid, 1.05 nkat/mg for 3-hydroxybenzoic acid, 0.77 nkat/mg for p-hydroxybenzoic acid, 1.69 nkat/mg for vanillic acid, 0.68 nkat/mg for 3,4-dimethoxycinnamic acid, 0.17 nkat/mg for phenylpropionic acid, 0.22 nkat/mg for phenylbutyric acid, 0.75 nkat/mg for 3-aminobenzoic acid, 1.73 nkat/mg for 4-aminobenzoic acid and 4.88 nkat/mg for UDP-glucose (with cinnamic acid). Enzyme activity is assayed in 100 mM Tris-HCL buffer, pH 8.0, containing 5 mM 2-mercaptoethanol, 10% glycerol, and 5 mM sodium disulfite. The aglycon concentration is varied from 2 microM to 2 mM, at constant (5 mM) UDP-Glc concentration at 21°C. |
