ASYMMETRY OF SUBUNITS OF ASPARTATE AMINOTRANSFERASE IN SOLUTION

Summary

    The apparent pK. of enzyme-bound pyridoxal-5'-phosphate of subunits determined by circular dichroismic pH titralion of the pyridoxal form of aspartate aminotransferase (EC 2.6.1.1) amounts to pK.1'=5.55±0.2, pK2'=6.87±0.14.
