| Abstract | 1. 1. T. thermophila ornithine decarboxylase was purified 1100-fold by an improved procedure to a specific activity of 2.31 × 10 4 nmol/hr/mg protein with a 28% yield. 2. 2. The purified enzyme was a monomer of M r = 68, 000 and had two isoelectric forms with pI's of 5.14 and 5.17 respectively. 3. 3. The M r = 68, 000 enzyme was reversibly modified by a cellular factor of approx. M r = 10, 000 to give rise to two additional forms with decreased DEAE-cellulose affinity. © 1987. |
