Enzymatic synthesis of 1-deoxysugar-phosphates using E. coli 1-deoxy-d-xylulose 5-phosphate synthase
摘要:
The thiamine diphosphate-dependent enzyme 1-deoxy-D-xylulose 5-phosphate synthase from E. coli can use D-erythrose 4-phosphate and D-ribose 5-phosphate as alternative substrates. These reactions were used for the production of 1-deoxy-D-fructose 6-phosphate and 1-deoxy-D-sedoheptulose 7-phosphate and have potential application for the biosynthesis of other 1-deoxysugar phosphates.

A green enzymatic strategy for the synthesis of terminally phosphorylated C5 to C9 naturally occurring D-ketose phosphates and analogues was developed using D-fructose-6-phosphate aldolase (FSA) as a catalyst. This enzyme has stereoselectively catalysed aldol reactions between glycolaldehyde phosphate or ribose-5-phosphate as an acceptor substrate and dihydroxyacetone, hydroxyacetone or hydroxybutanone as a donor. Furthermore, D-glycero-D-altro-2-octulose 8-phosphate was obtained using a straightforward one-pot domino biocatalytic system involving FSA, ribulose-5-phosphate epimerase and ribose-5-phosphate isomerase controlling five contiguous asymmetric centres and starting from achiral material.
