Comparison of glycolysis and glutaminolysis in Onchocerca volvulus and Brugia pahangi by 13C nuclear magnetic resonance spectroscopy

Abstract

Comparison of glycolysis in Brugia pahangi and Onchocerca volvulus by 13C nuclear magnetic resonance (NMR) spectroscopy showed that the former organism is predominantly a lactate fermenter and the latter resembles more closely the metabolism of a mixed acid fermenter producing lactate, succinate, acetate, ethanol, formate and carbon dioxide. Both organisms synthesize glycogen as a storage carbohydrate. Glutaminolysis in both organisms proceeds by the δ-amino-butyrate shunt to produce succinate which is then further metabolized to acetate and carbon dioxide as end-products. © 1989, Cambridge University Press.
