Models of metabolism in Rhizopus oryzae.

A flux analysis of glucose metabolism in Rhizopus oryzae was achieved using [14C]-labeled glucose and acetate. The rates of glucose utilization and end product production were estimated, and metabolite pool sizes and specific radioactivities were determined. These data were analysed using a specific radioactivity curve-matching program called TFLUX. The analysis is consistent with the existence of separate mitochondrial and cytosolic pools of pyruvate, malate and fumarate.
