Cobalt-activated acylase from human uterine myoma

Cobalt-activated acylase was isolated from human uterine muscle and myoma. The enzyme was purified by ammonium sulphate precipitation, and subsequent chromatography on DEAE-cellulose, Sephadex G-150 and DEAE-Sephadex. The comparison of muscle acylase and acylase obtained from myoma has shown differences in the enzyme stability, the dependence of activity on pH and in the susceptibility to the effect of activators and inhibitors. Only one molecular form of cobalt-activated acylase has been found in both tissues.
