1. D-Galactose dehydrogenase from Pseudomonas saccharophila (molecular weight 102 000) dissociates in 8 M urea into its subunits (molecular weight 25 000) which migrate in polyacrylamide gels, containing 8 M urea, as a single band. 2. The N-terminal residue determination by the dansyl method revealed only serine. 3. The C-terminal group determination with carboxypeptidase A and B indicated the sequence -Tyr-His-Leu. Leucine as the single C-terminal amino acid was confirmed by the tritiation method and by tritiation and subsequent degradation with carboxypeptidases. 4. The fragmentation of D-galactose dehydrogenase (24 mol methionine per mol enzyme) by CNBr resulted in six peptides, as detected in disc electrophoresis and substantiated by end group determination, indicating the identity of the subunits. 5. The treatment of D-galactose dehydrogenase (24 mol lysine and 52 mol arginine per mol enzyme) with trypsin and subsequent peptide mapping showed 21, perhaps 22 peptides, indicating a structure comprising four identical subunits.
