Description_x000D_ General description_x000D_ Oxaloacetate decarboxylase or OAD functions as a Na pump in anaerobic bacteria. It is a membrane protein consisting of three subunits, α, β and γ with the α subunit containing the carboxylase activity._x000D_ Application_x000D_ Oxaloacetate decarboxylase has been used in a study to assess turnover and accessibility of a reentrant loop of the Na(+)-glutamate transporter GltS. It has also been used in a study to investigate fermentation and metabolic characteristics of Gluconacetobacter oboediens for different carbon sources._x000D_ Packaging_x000D_ 500, 1000 units in glass bottle_x000D_ Unit Definition_x000D_ One unit will convert 1.0 μmole of oxalacetate to pyruvate and CO2 per min at pH 8.0 at 25 °C.
