Native Microorganisms Pyruvate Oxidase

Cat No.
NATE-0613
Description
Pyruvate Oxidase consists of four subunits with identical molecular weights. PoxB reacts with certain aldehydes and phosphate can be replaced by arsenate. Oxygen as well as several artificial compounds can function as electron acceptors. Pyruvate Oxidase is activated by phospholipids as well as monomeric and micellar amphiphiles.

Applications
Pyruvate Oxidase (PoxB) converts pyruvate directly to acetate and CO2. It is used to study pyruvate metabolism. It is used to study aerobic metabolism of bacterium, such as Lactobacillus plantarumand Strept oc occus pneumoniae. Pyruvate Oxidase is used for enzymatic determination of pyruvate, GOT, and GPT in clinical analysis.
