A simple purification for the membrane-associated, flavin-linked, glycerol-3-phosphate dehydrogenase of Escherichia coli has been developed which yields homogeneous enzyme in a detergent-solubilized state. 1. The dissociated form of the enzyme has a molecular weight of 58,000 and contains 0.5 mol of FAD/mol of protein monomer. 2. The solubilized enzyme-catalyzed reaction has a pH profile and te...

Glyceryl-ether monooxygenase (1-alkyl-sn-glycerol,tetrahydropteridine: oxygen oxidoreductase, EC 1.14.16.5) catalyzes the oxidative cleavage of 1-O-alkyl glycerol or glycol derivatives to a long-chain aldehyde and the glycerol or glycol derivative. The specificity for tetrahydropterins of a similar, perhaps identical, enzyme that cleaves O-hexadecyl ethylene glycol in rat liver microsomes was e...
