Table 1. Comparison of Assay Enzymes and Preliminary Screening Data.
Data are the means of measurements in three technical replicates.
[Compound] = 250 μM, [ThDP] = 50 μM.
[Compound] = 1.5 mM, [ThDP] = 0.3 mM; compounds insufficiently soluble were excluded. (The KM of yeast PDC for ThDP was found to be 11–23 μM, so a high [ThDP] was needed to fully saturate the enzyme.)
