Streptokinase catalyzes hydrolysis of amide linkages. Forms a 1:1 complex with plasminogen which is then converted to streptokinase-plasmin. Both streptokinase-plasminogen and streptokinase-plasmin complexes can activate plasminogen. As a result of its interaction with human or rabbit plasminogen, streptokinase undergoes specific fragmentation.

The hyaluronidase is purified from Streptomyces hyalurolyticus. This enzyme belongs to the endo-beta-hexosaminidase and endo-eliminase type enzyme that produces oligo-saccharide (unsaturated tetraose and pentose) by hydrolysing the beta-1,4-linkage of hyaluronic acid. It is stable in both high temperature and acid or alkaline range. It has high substrate specificity and hydrolyzes hyaluronic acid only in mucopolysaccharide.

Aldolase is a tetrameric protein. It catalyses a key reaction in glycolysis and energy production:D-Fructose 1,6-bisphosphate aldolase → dihydroxyacetone phosphate + D-glyceraldehyde-3-phosphate. Aldolase is present in all animal tissue and in most microorganisms. There are two classes of aldolases. Class I aldolase is found in animal and higher plant tissue. Class II aldolase is found in primitrive cells such as yeasts and bacteria. Class I aldolase is characterised by not requiring a bivalent metal cofactor and the formation of a ketimine Schiff base intermediate with the substrate dihydroxyacetone phosphate. Class II aldolase requires a metal cofactor and is inhibited by EDTA. Three types of aldolase exist in animal tissue. The major form, type A is found in muscle; type B is found in liver tissue and type C (plus some type A) is found in brain tissue. Aldolase forms five isozymes which may to various degrees be organ specific.
