[Valyl- and alanyl-tRNA-synthetase activity in the skeletal muscles of the rabbit in diabetes and during insulin administration].

Activities of alanyl- and valyl tRNA synthetases were considerably higher in rabbit muscle soleus than in muscle gastrocnemius. Repeated injections of insulin into normal rabbits as well as impairment of animals by experimental alloxan diabetes within two weeks did not alter significantly the activity of the synthetases in red and mixed muscles.
