pubmed-article:3935171 | pubmed:abstractText | A new method for purification and crystallization of pig skeletal muscle phosphorylase b is presented. The ease of crystallization in the presence of 1 mM AMP and 1 mM spermine has permitted the study of some physical, chemical and enzymatic properties of the enzyme. The crystalline pig phosphorylase b gave a single band on SDS polyacrylamide gels of the same mobility as rabbit muscle phosphorylase subunit. Ultracentrifugation experiments showed that pig phosphorylase b exists in a dimeric form (S20,w = 8.4 S). No association occurred at 20 degrees C under conditions where rabbit phosphorylase b can be tetramerized; pig phosphorylase b was only 30% associated from dimer to tetramer at 13 degrees C. Pig phosphorylase b is highly stable to freezing and its specific activity did not change appreciably upon prolonged storage in the cold. Pig and rabbit phosphorylases b have comparable Vmax and Km values towards the substrate and the activator. However, there is an essential difference between the two enzymes in that pig phosphorylase b is not significantly inhibited by glucose 6-phosphate, which is a powerful inhibitor of the rabbit enzyme. Two different crystal forms of pig phosphorylase b were obtained which are small for X-ray diffraction studies. Diffusion of spermine into tetragonal crystals of rabbit phosphorylase b resulted in a difference Fourier synthesis at 3 A resolution that showed no strong indication of specific binding. | lld:pubmed |
