Description

Transaldolase (EC:2.2.1.2) catalyses the reversible transfer of a three-carbon ketol unit from sedoheptulose 7-phosphate to glyceraldehyde 3-phosphate to form erythrose 4-phosphate and fructose 6-phosphate. This enzyme, together with transketolase, provides a link between the glycolytic and pentose-phosphate pathways. Transaldolase is an enzyme of about 34 kDa whose sequence has been well conserved throughout evolution. A lysine has been implicated [PMID: 8109173] in the catalytic mechanism of the enzyme; it acts as a nucleophilic group that attacks the carbonyl group of fructose-6-phosphate.

This entry represents transaldolases type 2, which is found in bacteria and plants.
