UDPglucose dehydrogenase from Escherichia coli has been purified 330-fold with an overall yield of 27%. A single homogeneous subunit was demonstrated by ultracentrifugation in 6 M guanidium chloride and by dodecyl sulfate-polyacrylamide gel electrophoresis. Since the molecular weight of the intact dehydrogenase is in the order of 86 000 and the subunit weight determined by the dodecyl sulfate-polyacrylamide gel electrophoresis is 47 000, the enzyme consists of two polypeptide chains. The sole amino terminal acid shown by the dansylation technique was arginine. Forty-four tryptic peptides were obtained by peptide mapping, in agreement with the number of arginine and lysine residues/mole protein [43] determined by amino acid analysis. The data are consistent with the presence of two identical or very similar polypeptide chains in E. coli UDPglucose dehydrogenase.
