Substrate specificity. The substrate specificity of VDH was determined by measuring the enzyme activity at the optimal pH, 9.5, under otherwise standard assay conditions. The measured activity in each case is expressed here as the percentage of activity toward vanillin, and the data are shown as means ± standard deviation (error bars; n = 3). Abbreviations: VAL, vanillin; IVA, isovanillin; VER, veratraldehyde; SYR, syringaldehyde; ANS, anisaldehyde; PCA, protocatechualdehyde; PHB, p-hydroxybenzaldehyde; SAL, salicylaldehyde; BAL, benzaldehyde
