Description
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. The following chemical reaction is catalyzed by transaldolase:sedoheptulose 7-phosphate + glyceraldehyde 3-phosphate↔ erythrose 4-phosphate + fructose 6-phosphate.
Abbr
Transaldolase, Native (Baker's Yeast (S. cerevisiae))
Source
Baker's yeast (S. cerevisiae)
Applications
Useful in systems requiring low sulfate concentrations.
Form
Lyophilized, essentially sulfate-free; contains approx. 5% Citrate buffer salts
Enzyme Commission Number
EC 2.2.1.2
Activity
10-30 units/mg protein (biuret)
Unit Definition
One unit will produce 1.0 μmole of D-glyceraldehyde 3-phosphate from D-fructose 6-phosphate per min in the presence of D-erythrose 4-phosphate, at pH 7.7 at 25°C in a coupled system with GDH/TPI and β-NADH.
