Alcohol dehydrogenases are a group of dehydrogenase enzymes that occur in many organisms. It is a metalloenzyme containing four tightly bound zinc atoms per molecule. Each subunit also contains a second zinc atom (conformational zinc), which stabilizes the enzyme’s tertiary structure. Per subunit, there are two distinct active site sulfhydryl groups which can be distinguished on the basis of differential reactivity with iodoacetate and butyl isocyanate. A histidine residue is considered to have an essential role.

Aprotinin is found in bovine lymph nodes, lung, parotid gland, spleen, liver, pancreas, seminal vesicles, thyroid gland, kidney, mucous membranes of the trachea and esophagus, ovaries, heart, posterior pituitary and cartilage. It is a serine protease inhibitor which is reactive against trypsin, chymotrypsin, plasmatic and glandular kininogenases, plasmin, kallkrein, urokinase, clotting factor XIIa, protein C, proteinases of the complement system, leukocyte and tissue proteinases. It does not inhibit thrombin. Aprotinin works by blocking the active sites of enzymes. Binding is reversible with most aprotinin-protease complexes dissociating at pH > 10 or < 3.

Deoxyribonuclease from beef pancreas, DNase I, was first crystallized by Kunitz. It is an endonuclease which splits phosphodiester linkages, preferentially adjacent to a pyrimidine nucleotide yielding 5'-phosphate terminated polynucleotides with a free hydroxyl group on position 3'. The average chain of limit digest is a tetranucleotide. DNase I acts upon single chain DNA, and upon double-stranded DNA and chromatin. In the latter case, although histones restrict susceptibility to nuclease action, over a period of time nearly all chromatin DNA is acted upon. According to Mirsky and Silverman, this could result from the looseness of histone attachment to DNA. They found that lysine-rich histones more effectively block DNase access to DNA than arginine-rich histones. Billing and Bonner suggest that DNase attacks the histone-free strand of chromatin DNA. Schmidt, et. al.indicate that hydrolysis of the histone-free region of DNA strands accounts for the initial rapid action of the enzyme on chromatin. Bollum reports degradation of synthetic homopolymer complexes by DNase I. The intracellular functions of the enzyme are probably controlled by a DNase inhibitor, which according to Lazarides and Lindberg is actin.
