Adenosine 5'-triphosphate-arginine phosphotransferase from lobster muscle. Molecular weight.
1. The molecular weight of arginine kinase from lobster muscle has been determined by three procedures: ultracentrifuge analysis, gel filtration and density-gradient centrifugation. 2. The three methods give similar results and the best estimate of the molecular weight is 37000. 3. The enzyme does not readily show association-dissociation phenomena. 4. The usefulness of density-gradient centrifugation for determinations of molecular weight is briefly discussed.
