Transaldolases including both TalA and TalB. The enzyme catalyses the reversible transfer of a dyhydroxyacetone moiety, derived from fructose-6-phosphate to erythrose-4-phosphate yielding sedoheptulose-7-phosphate and glyceraldehyde-3-phosphate. The catalytic mechanism is similar to other class I aldolases. The enzyme is found in the non-oxidative branch of the pentose phosphate pathway and forms a dimer in solution.
