| Abstract: | Ascaridia galli, using 2-oxoglutarate as an acceptor, transaminates alanine and aspartate at significantly high rates. Among other amino acids valine, phenylalanine, leucine, isoleucine, arginine, tyrosine and methionine are metabolised at moderate rates while lysine, serine, threonine, cysteine, glycine, histidine, tryptophan, DOPA and GABA appear to be inert in this respect. Body parts mimic the whole worm in the pattern of transamination of various amino acids with the exception of methionine. Alanine, aspartate and glutamate may transfer their amino group also to pyruvate and oxaloacetate. Alanine and aspartate: 2-oxoglutarate transaminases are located mainly in the cytosol and mitochondrial fractions. |
