Activity of Aspartate Carbamoyltransferase in Ovine Tissues

Abstract

The activity of the enzyme aspartate carbamoyltransferase (ACT; EC 2.1.3.2) was studied in ovine tissues. Hepatic, ileal and duodenal tissues showed higher levels of activity (6-19 units) than skeletal muscle, cardiac muscle, lung, spleen, kidney and rumen wall (2-7 units). Low growth impetus skeletal muscles had higher activity (2·9 units) than high growth impetus muscles (1·8 units) taken from immature sheep but such differences were not present in mature sheep.
