IN the course of work on the transamination reactions between aspartate and alpha-ketoglutarate mediated by extracts of the gland and intestines of the silkworm, Bombyx mori L., an entirely new ninhydrin-positive spot with an $R_F$ value different from either the glutamate produced or added aspartate was observed when the reaction mixture was resolved on Whatman No. 1 filter paper employing butanol/formic acid/water (10 : 2 : 5) as the solvent. It was suggested that this additional spot represents a peptide produced by enzymic transpeptidation; but further work on transpeptidation with glycyl peptides and glutathione as the substrates did not confirm this view. A more detailed examination has therefore been made of the circumstances giving rise to this additional spot.
