Alpha-glycerophosphate oxidase in Streptococcus faecium F 24.

alpha-Glycerophosphate oxidase, in a strain of Streptococcus faecium, was found to be adaptive to aerated conditions of growth. The enzyme was purified and found to mediate electron transfer from alpha-glycerophosphate to O(2), with the production of stoichiometric concentrations of H(2)O(2) and dihydroxyacetone phosphate. The enzyme is an anionic flavoprotein, with flavine adenine dinucleotide as the apparent prosthetic group.
