Transaldolase is an enzyme (EC 2.2.1.2) of the non-oxidative phase of the pentose phosphate pathway. In humans, transaldolase is encoded by the TALDO1 gene.Reaction scheme for the conversion of sedoheptulose-7-phosphate to fructose-6-phosphate.The pentose phosphate pathway adapted from (Verhoeven, 2001) Transaldolase is an enzyme (EC 2.2.1.2) of the non-oxidative phase of the pentose phosphate pathway.
