Purification of alpha-glycerophosphate dehydrogenase from Drosophila melanogaster. 1976

G E Collier, and D T Sullivan, and R J MacIntyre

A simple procedure has been devised for the purification of alpha-glycerophosphate dehydrogenase (EC 1.1.1.8) FROM Drosophila melanogaster. The method involves substrate elution of the enzyme from a carboxymethyl cellulose column, followed by salt elution from agarose-hexane-AMP and DEAE columns. The procedure requires only 3 days to complete, results in high yield, and preparations that appear homogeneous by several criteria. A subunit molecular weight of 31 700 was obtained by sodium dodecyl sulphate electrophoresis in 10% acrylamide gels. This value is half that published for the native enzyme, confirming the homodimeric structure of this enzyme suggested by genetic evidence.

D004331 Drosophila melanogaster A species of fruit fly frequently used in genetics because of the large size of its chromosomes. D. melanogaster,Drosophila melanogasters,melanogaster, Drosophila
D004589 Electrophoresis, Disc Electrophoresis in which discontinuities in both the voltage and pH gradients are introduced by using buffers of different composition and pH in the different parts of the gel column. The term 'disc' was originally used as an abbreviation for 'discontinuous' referring to the buffers employed, and does not have anything to do with the shape of the separated zones.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
