Colorful activity: A new pH‐sensitive assay method has been developed for a reliable high‐throughput measurement of transketolase activity. Wild‐type and engineered enzymes were evaluated with a panel of substrate analogues. Substrate quality was verified by preparative synthesis of chiral deoxyketose‐type products, with ee determination by chiral GC analysis.

The behaviour and the specificity of a spinach transketolase towards achiral aldehydes was studied. We have shown that these aldehydes are accepted by the enzyme and yield the corresponding saccharides with good enantiomeric excess.
