Amino acid catabolism in the nematodesHeligmosomoides polygyrusandPanagrellus redivivus2. Metabolism of the carbon skeleton

Abstract

SUMMARYAll of the enzymes of proline catabolism were present inHeligmosomoides polygyrusandPanagrellus redivivusand the activities were, in general, similar to those found in rat liver. Both nematodes were also shown to be able to catabolize the branched-chain amino acids leucine, isoleucine and valine, by pathways similar to those found in mammalian liver. There were no significant differences in amino acid catabolism between the animal-parasitic and free-living species of nematode.
