Abstract

The seeds of Lathyrus sativus contain the unusual amino acid homoarginine. The possible breakdown of homoarginine to lysine and urea has been investigated with enzyme extracts prepared from the seedlings of L. sativus. The results indicate that there is no separate homoarginase enzyme but that the arginase present has about 5 per cent activity towards Image -homoarginine as compared to that obtained with Image -arginine. The enzyme does not show an absolute dependence on Mn2+ for activity and maximal activation of the enzyme has been realized with Fe3+. It is concluded that the breakdown of homoarginine through the urea cycle may only represent a minor pathway for the catabolism of this compound in this plant.
