Rat liver cysteine sulfinate decarboxylase: purification, new appraisal of the molecular weight and determination of catalytic properties.

Rat liver cystein sulfinate decarboxylase (L-cystein sulfinate carboxylase) was purified approximately 500-fold. By cellulose acetate and polyacrylamide gel electrophoresis or by analytical ultracentrifugation, the purified enzyme appears to be nearly homogeneous. The Stokes radius (3.
