Association of the dimeric form to the decamer is concomitant with the increase in ionic strength 37289 4.1.1.18 80000 - x * 80000, SDS-PAGE, high-speed sedimentation equilibrium in presence of 6 M guanidine HCl. Subunits associate or dissociate reversibly as a function of pH and ionic strength. The native decameric form is formed by the cyclic association of five dimers. Its overall appearance is that of two stacked pentameric rings. Higher aggregates result from the linear stacking of decamers to form rodlike particles of indefinite length 37293 4.1.1.18 81000 - 10 * 81000, X-ray crystallography 716768 4.1.1.18 82000 - SDS-PAGE 690597 4.1.1.18 85000 - x * 85000, SDS-PAGE 727766 4.1.1.18 88000 - gel filtration 37290, 654982 4.1.1.18 95000 - gel filtration 37297 4.1.1.18 150000 - gel filtration 728013 4.1.1.18 154000 - dimeric enzyme form, sedimentation data 37289 4.1.1.18 158000 - dimeric enzyme, native PAGE 748418 4.1.1.18 422000 - pentameric enzyme form, native PAGE 37283 4.1.1.18 531000 - gel filtration 37300 4.1.1.18 545000 - heptameric enzyme form, gel filtration 37283 4.1.1.18 730000 - decameric enzyme form, sedimentation data 37289 4.1.1.18 761000 - decameric enzyme form, analytical ultracentrifugation at 6800 rpm 37283 4.1.1.18 780000 - decameric enzyme, native PAGE 748418 4.1.1.18 795700 - decameric enzyme form, analytical ultracentrifugation at 3600 rpm 37283 4.1.1.18 800000 - gel filtration 37299 4.1.1.18 1000000 - equilibrium sedimentation 37294, 37295 4.1.1.18 1174000 - pentadecameric enzyme form, analytical ultracentrifugation at 2600 rpm 37283
