Fig. 5From: Hydrogen peroxide-producing pyruvate oxidase from Lactobacillus delbrueckii is catalytically activated by phosphotidylethanolamineL. delbrueckii does not co-precipitate with PE. L. delbrueckii Pox with 50 mM pyruvate, 300uM TPP, and 15uM FAD was incubated with 1 mM PE or no lipid. The lipid fraction was pelleted by centrifugation after 30 min. Shown is a Coomassie stain of either the lipid pellet fraction (P) or the soluble fraction (S)Back to article page
