Amino acid metabolism of Astacus leptodactylus (Esch.)—II. Biosynthesis of the non-essential amino acids

Abstract

1. 1. Incubation of Astacus leptodactylus with U-14C-glucose or 1-14C-acetate induced labelling of α- and β-alanine, aspartic and glutamic acids, glutamine, glycine, proline and serine. No radioactivity was incorporated into arginine, asparagine, histidine, isoleucine, leucine, lysine, ornithine, phenylalanine, taurine, threonine, tyrosine and valine.

2. 2. From the results obtained the biosynthetic pathways for the non-essential amino acids in A. leptodactylus are discussed.
