Abstract: | Oxaloacetate, a competitive inhibitor of succinate dehydrogenase, bound with a sulfhydryl group of the enzyme to abolish the enzymic activity. Subsequently a thiosemiacetal was apparently formed to render the inhibition practically irreversible. The dehydrogenase, after taking up 25 silver equivalents per flavin, bound little oxaloacetate. |
