A crude cell-free extract of a skeletal muscle contained 32 mg protein/ml. Ten ul (microlitres) of the extract catalyzed a reaction at rate of 0.14 umole/min under standard optimum assay conditions. Fifty ml of the extract were fractionated by ammonium sulphate precipitation. The supernatant obtained after centrifugation was redissolved in […]
