description

Glutamic dehydrogenase of rat liver mitochondria is inhibited by phenylbutazone at a final concentration of 2,5 mg-% (0,81 · 10−4 M). However, glutamic dehydrogenase in heart muscle homogenate and the cristalline enzyme from liver are not inhibited by phenylbutazone up to 10 mg-% (3,24 · 10−4 M), but they are inhibited by a metabolite arising during incubation of liver mitochondria with phenylbutazone.
