Comparisons of relative specific activities of petunia BPBT with a variety of substrates. Black and white bars represent activities with acetyl-CoA and benzoyl-CoA, respectively, and indicated alcohol cosubstrates. In both cases activity with benzyl alcohol was set to 100% and was 10.2 ± 1.2 nkat/mg protein and 19.7 ± 3.4 nkat/mg protein in presence of acetyl-CoA and benzoyl-CoA, respectively. Alcohol substrates were as follows: 1, benzyl alcohol; 2, 3-hydroxy-benzyl alcohol; 3, 4-hydroxy-benzyl alcohol; 4, 2-phenylethanol, 5, cinnamyl alcohol; 6, geraniol; 7, linalool; 8, ethanol; 9, butanol; 10, 2-hexanol; 11, 3-hexanol; 12, cis-3-hexen-1-ol; and 13, 1-octanol. Each point is the average of three independent experiments. se values are indicated by vertical bars.
