FRAGMENT K 2-3 OF PLASMINOGEN MOLECULE CARRIES A LYSINE-B1NDING SITE
Summary
Limited pepsin digestion of plasminogen fragment K 1-3 leads to the formation of the first kringle and structure which contains the second and third kringles (fragment K 2-3). The isolated fragments are characterized according to molecular masses and ami-no acid composition. Fragment K 2-3 is shown to be able of binding with lysine-Sepha-rose, which indicates the existence of a lysine-binding site in its structure.
