P00750 TPA_HUMAN Specific cleavage of Arg-|-Val bond in plasminogen to form plasmin. Heterodimer of chain A and chain B held by a disulfide bond. Binds to fibrin with high affinity. This interaction leads to an increase in the catalytic efficiency of the enzyme between 100-fold and 1000-fold, due to an increase in affinity for plasminogen. Similarly, binding to heparin increases the activation of plasminogen. Binds to annexin A2, cytokeratin-8, fibronectin and laminin. Binds to mannose receptor and the low- density lipoprotein receptor-related protein (LRP1), these proteins are involved in TPA clearance. Yet unidentified interactions on endothelial cells and vascular smooth muscle cells (VSMC) lead to a 100-fold stimulation of plasminogen activation. In addition, binding to VSMC reduces TPA inhibition by PAI-1 by 30-fold. Binds LRP1B, binding is followed by internalization and degradation. Secreted, extracellular space.
P98119 URT1_DESRO Specific cleavage of Arg-|-Val bond in plasminogen to form plasmin. Monomer. Secreted.

Comments
This enzyme belongs to the peptidase family-S1.
This enzyme is composed of six domains; fibronectin type-I domain, EGF-like domain, Kringle1 domain, Kringle2 domain and catalytic domains of serine protease.
The PDB structures correspond to the following domains.
(PDB;1tpg, Swiss-prot;P00750, residues 36-126 [EGF-like/Kringle1 domain],
PDB;1pk2, Swiss-prot;P00750, residues 209-297 [klingle2 domain],
PDB;1a5hA, Swiss-prot;P00750, residues 311-562 [Catalytic domain]).
As this enzyme has got a classical catalytic triad composed of Ser/His/Asp, which is the same as that of trypsin (D00197 in EzCatDB), it should have a similar mechanism.
