Allgemeine Beschreibung

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.

Anwendung

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. Wirkung

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.

The oxaloacetate decarboxylase Na+ pumps OAD-1 and OAD-2 of Vibrio cholerae are composed of a peripheral alpha-subunit associated with two integral membrane-bound subunits (beta and gamma). The alpha-subunit contains the carboxyltransferase domain in its N-terminal portion and the biotin-binding domain

The oxaloacetate decarboxylase primary Na(+) pump (OAD) is an essential membrane protein complex that functions in the citrate fermentation pathway of some pathogenic bacteria under anaerobic conditions. OAD contains three different subunits: Oad-α, a biotinylated extrinsic protein that catalyzes the
