General description
Diethyl pyrocarbonate (DEP) is a bactericidal agent and decomposes in water to CO2 and ethanol. DEP inhibits enzymes such as DNase and RNase without affecting nucleic acids. It is useful for the preparation of mRNA from tissues.
Application
Diethyl pyrocarbonate may be used in the following studies:
- For the modification of histidyl residues in proteins.
- As a nuclease inhibitor, for the extraction of undegraded nucleic acids from etiolated and green plant tissues.
- For the modification of linear and supercoiled plasmid DNAs.
- As a chemical probe to investigate the secondary structure in negatively supercoiled DNA.
- For cabethoxylation of histidine residues of actin.
Modification reagent for His and Tyr residues in proteins. Robust probe for structural disruptions in dsDNA, reacting with fully or partially unstacked bases.
Biochem/physiol Actions
Inactivates RNase in solution at about 0.1% (v/v), thus protecting RNA against degradation.

Purine residues located within regions of DNA that have the potential to form left-handed Z-helical structures are modified preferentially by diethyl pyrocarbonate; this hyperreactivity is dependent on the degree of negative superhelicity of the circular DNA molecules. As negative superhelical
