Exonuclease I acts specifically on single-stranded DNA degrading it processively in the 3'- to 5'-direction, producing 5'-mononucleotides. Applications include eliminating residual single-stranded DNA containing a 3'-terminus, measuring endonucleolytic cleavage of covalently closed circular (ccc) ssDNA, measuring DNA helicase activity.

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.

Activators: Papain is activated by cysteine, sulphide, sulphite and more. It is enhanced when heavy metal binding agents such as EDTA are also present. N-bromosuccinimide enhances the activity. Inhibitors: Substances which react with sulphydryl groups including heavy metals, carbonyl reagents. Aldehydes are papain inhibitors. Benzoylamidoacetonitrile is an inhibitor. See Shapira and Arnon (1967a and b) on antibody inhibitors. Papain may be inactivated by H₂O₂ generated by γ-irradiation of H₂O⁻ the active SH group being oxidised to sulphenic acid. Specific inhibitors are AEBSF, antipain, cystatin, E-64, leupeptin, PMSF, TLCK and TPCK.
