3.4.21.7	additional information	Glu-plasminogen incubated with adherent cells, i.e. CHO-K1, HEK-293 and HMEC-1 cells, is converted into plasmin for activation by constitutively expressed tPA, i.e. tissue-type plasminogen activator, or uPA, i.e. urokinase-type plasminogen activator	717216	
3.4.21.7	additional information	staphylokinase, SAK, forms a 1:1 stoichiometric complex with human plasmin and switches its substrate specificity to generate a plasminogen activator complex with a crucial requirement of a positively charged and an aromatic residue, respectively, at positions 43 and 44, i.e. SAKHis43 and SAKTyr44, for optimal functioning of SAK-Pm activator complex. Role of these residues in making cation-pi and pi-pi interactions with Trp215 of plasmin and thus establishing the crucial intermolecular contacts within the active site cleft of the activator complex for the cofactor activity of staphylokinase.

3.4.21.7	additional information	the increased activity of plasmin after diafiltration may be also due to elimination of small enzyme inhibitor proteins	717666	
3.4.21.7	additional information	the main physiological activators of plasminogen are tissue-type plasminogen activator, which is mainly involved in the dissolution of the fibrin polymers by plasmin, and urokinase-type plasminogen activator, which is primarily responsible for the generation of plasmin activity in the intercellular space. Both activators are multidomain serine proteases	717469
