though this assembled but inactive form of core enzyme harbors the gross conformation similar to that of native enzyme , minor and presumably local differences exist , which were identified by near-ultraviolet circular dichroism spectra , tritium-hydrogen exchange rate , protease sensitivity , intersubunit cross-linking rate by bifunctional reagents , sedimentation behavior , and elution profile from phosphocellulose .
