title: Temporal relationships in the effects of protein-free diet on the activities of rat liver branched-chain ketoacid dehydrogenase complex and kinase.
abstract: Feeding rats 0% casein diet decreased liver activities of branched-chain ketoacid dehydrogenase complex (active form) and of activator protein (complete within 4 days), and increased activity of branched-chain ketoacid dehydrogenase kinase (complete within 9-10 days). Refeeding normal diet to rats fed 0% casein diet for 10 days resulted in a rapid and partial (approx. 50%) reversal of the above effects within 24 h; complete reversal required 20-30 days of refeeding.
