A finger region an epidermal growth factor like sub domain two kringle domains and finally the catalytic domain.

Kringle domain. Kringle domains are believed to play a role in binding mediators e g membranes other proteins or phospholipids and in the regulation of proteolytic activity. They are found in a varying number of copies in some plasma proteins including prothrombin and. The kringle domains mediate the interaction of plasminogen and its active form plasmin with substrates inhibitors and cell membranes.

Kringle domains consist of approximately 80 amino acid residues with three disulfide bonds. Kringle domains 4 5 6 are characterised by a triple loop 3 disulphide bridge structure whose conformation is defined by a number of hydrogen bonds and small pieces of anti. Tpa is composed of five distinct structural domains.

Kringle domains pubmed 3131537 pubmed 3891096 pubmed 1879523 are characterised by a triple loop 3 disulphide bridge structure whose conformation is defined by a number of hydrogen bonds and small pieces of anti parallel beta sheet.

Human tissue plasminogen activator expression in escherichia coil using cytoplasmic and periplasmic cumulative power. Kringle ˈ k r ɪ ŋ ɡ əl listen help info is a scandinavian pastry a nordic variety of pretzel. These are important in protein protein interactions with blood coagulation factors.

The name kringle comes from the scandinavian pastry that these structures resemble. Kringle domains are believed to play a role in binding mediators e g membranes other proteins or phospholipids and in the regulation of proteolytic activity. Pretzels were introduced by roman catholic monks in the 13th century in denmark and from there they spread throughout scandinavia and evolved into several kinds of sweet salty or filled pastries all in the shape of kringle.

Consequently the kringle domains are important in both regulation of plasminogen activation and the localization of the proteolytic activity of plasmin to the appropriate physiological site wu et al 1990. Kringle domains have been found in plasminogen hepatocyte growth factors prothrombin and apolipoprotein a. Kringle domains are autonomous protein domains that fold into large loops stabilized by 3 disulfide linkages.
