title: Molecular structure of exonuclease I from Escherichia coli B.
abstract: Exonuclease I of Escherichia coli B (EC 3.1.4.25) was determined to be a monomeric protein of molecular weight approx. 72,000, as estimated by Sephadex gel filtration, sedimentation velocity centrifugation, and sodium dodecylsulfate polyacrylamide gel electrophoresis.
