the rate of activation of plasminogen by pro-uk is not significantly influenced by the presence of 6-aminohexanoic acid , purified fragments lbs i or lbs ii or histidine-rich glycoprotein , indicating that the high affinity of pro-uk for plasminogen is not mediated via the high-affinity lysine-binding site of plasminogen located in kringles 1-3 ( lbs i ) nor via the low-affinity lysine-binding site comprised within kringle 4 ( lbs ii ) .
