MATERIALS AND METHODSGlycogen phosphorylase A from rabbit muscle (GPA) 1 was from Boehringer Mannheim (Lot 108 651). The enzymes were dissolved in the standard buffer: 0.05 M Tris, pH 7.5, 0.001 M inboth EDTA and DTT. Particulatematter of size greater than 2 µ was removed by a syringe filter. Protein concentration was determined spectrophotometrically using a specific absorptivity at 280 nm of 12.7 OD units for 1-cm depth of 1% solution (Graves & Wang, 1972). Enzyme activity was assayed by the method of Illingworth and Cori (1953). At 30 C and pH 6.8 the specific activity was found to be 79 units/mg, one unit being defined as the amount of enzyme causing the release of 1 µ of inorganic phosphate from glucose 1-phosphate per minute. AMP, glycogen, and glucose phosphate were from Sigma; 2-(dimethylamino) naphthalene-5-sulfonyl chloride (DNS-C1), 1-anilinonaphthalene-8-sulfonate (ANS), succinimidopyrene butyrate (SPB), and fluorescein 5-isothiocyanate (FITC) were from Molecular Probes. All other reagents were of analytical grade. Distilled water was further purified by a Millipore system to a resistance of 18.
