The activities of rhodanese and /Z-mercaptopyruvate sulfurtransferase (MST) in different
organs of sheep and cattle were measured.
2. Liver, kidney, omasum, and rumen were the richest sources of both enzymes. The activities of both
enzymes in other organs of the sheep and the cattle decreased in the order of lung, brain, heart, abomasum,
lymph node, urinary bladder, spleen, and the skeletal muscle.
3. The activities of both enzymes in most organs of the sheep were higher than the cattle.
4. Both enzymes showed higher activities in the epithelial layers than the muscular layers of rumen,
omasum and reticulum.
5. In most of the tissues of both species the level of rhodanese activity was greater than MST.
