Pyruvate Oxidase, Microorganisms
Based on 1 Customer Validation
Pyruvate Oxidase, Microorganisms (PoxB) is a peripheral membrane enzyme, isolated from microorganisms. Pyruvate oxidase catalyzes the oxidative decarboxylation of pyruvate to acetyl phosphate, carbon dioxide and water. Pyruvate oxidase is an important enzyme in bacterial metabolism and is often used in biochemical research.

Biological Activity
Pyruvate Oxidase contributes to stationary-phase acetate accumulation in Escherichia coli K-12 strain JRG3456[2].
Pyruvate Oxidase (50 mM phosphate buffer; 10 min) has an initial activity optimum at 38°C, but is unstable at temperatures above 30°C, with activity declining after 10 min of incubation at temperatures exceeding 30°C[4].
Pyruvate Oxidase (0.1-150 mM) exhibits highest activity with pyruvate, reacts with methylglyoxal and acetaldehyde[4].
Pyruvate Oxidase (1-10 mM) is only slightly inhibited by 10 mM EDTA (11%) and 10 mM KCN (25%), and is unaffected by 10 mM NaN3, 1 mM iodoacetamide, or 1 mM p-hydroxymercuribenzoate[4].
Pyruvate oxidase requires TPP, FAD, and a divalent cation (e.g., Mn2+) to catalyze the four-step oxidative decarboxylation of pyruvate, producing acetylphosphate and H2O2 to support aerobic lactobacterial growth[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
