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.
Enzyme-catalyzed synthesis of carbohydrates: synthetic potential of transketolase
The synthetic potential of yeast or spinach transketolases was studied, using hydroxypyruvate as a donor substrate and 31 aldehydes as acceptors. All of them react, including aromatic, heteroaromatic and alpha,beta unsaturated aldehydes.

A biological route to natural 6-deoxy-L-sorbose is described. This method is based on the production of natural hydroxypyruvate and 4-deoxy-L-threose and their conversion into 6-deoxy-L-sorbose: hydroxypyruvate is obtained from L-serine by serine : glyoxylate aminotransferase catalysis, 4-deoxy-L-threose is obtained by microbial isomerization of 4-deoxy-L-erythrulose, this last being obtained from
