title: Amino acid sequence of the carboxy-terminal end of human erythrocyte glucose-6-phosphate dehydrogenase.
abstract: Human erythrocyte glucose-6-phosphate dehydrogenase was purified to homogeneity by a simplified procedure, consisting of 2',5'-ADP-Sepharose affinity chromatography, followed by Sephadex G-100 gel filtration. The carboxy-terminal region of the protein was identified by carboxypeptidase digestion: the sequence -Lys-Leu-COOH was found instead of the reported -Gly-COOH, thus showing identity with the carboxy-terminal sequence of glucose-6-phosphate dehydrogenase from human leukocytes and platelets. In addition, the carboxyl-terminal peptide was isolated from a tryptic digest of the protein and sequenced. The sequence is: Trp-Val-Asp-Pro-His-Lys-Leu.
