General description

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.

Application

Oxaloacetate Decarboxylase from Pseudomonas sp. has been used in the digestion of the low molecular weight (LMW) human milk fraction (5kF fraction) and as a positive control for deciphering C. thermocellum oxaloacetate decarboxylase activity.
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.

Biochem/physiol Actions

Oxaloacetate Decarboxylase catalyzes the decarboxylation of oxaloacetate and requires manganese and magnesium for its activity. It is associated with a wide vareity of Gram-negative bacteria.

Unit Definition

One unit will convert 1.0 μmole of oxalacetate to pyruvate and CO2 per min at pH 8.0 at 25 °C.

Archaeoglobus fulgidus harbors three consecutive and one distantly located gene with similarity to the oxaloacetate decarboxylase Na+ pump of Klebsiella pneumoniae (KpOadGAB). The water-soluble carboxyl transferase (AfOadA) and the biotin protein (AfOadC) were readily synthesized in Escherichia coli, but the

The oxaloacetate decarboxylase (OAD) Na(+) pump consists of subunits alpha, beta, and gamma, which are expressed from an oadGAB gene cluster present in various anaerobic bacteria. Vibrio cholerae has two copies of oad genes, which are termed oad-1 and oad-2.
