Cytochrome P450 2E1 also known as CYP2E1 is an enzyme belonging to the cytochrome P450 superfamily. It weighs approximately 56 kDa. This enzyme is majorly expressed in the liver but can also be found in other tissues like the kidney and lungs. It plays a central role in the oxidation and metabolism of various endogenous and exogenous substances including fatty acids drugs and alcohols.

Biological function summary

The enzyme CYP2E1 metabolizes low-molecular-weight compounds. It catalyzes the conversion of substrates to more soluble forms enabling their excretion from the body. It is not a part of a larger protein complex but often partners with NADPH-cytochrome P450 reductase in electron transfer. CYP2E1 can also produce reactive oxygen species during its catalytic cycle which may impact cellular structures and processes.

Pathways

CYP2E1 is involved in the oxidative metabolism of ethanol and other xenobiotics. It participates in the metabolic pathways for drugs and carcinogens transforming them into either active or inactive metabolites. The enzyme has connections with other P450 enzymes such as CYP3A4 within the same metabolic landscape often overlapping substrates and regulatory mechanisms.

CYP2E1 plays a significant role in alcohol-induced liver injury because its metabolism of ethanol generates toxic by-products like acetaldehyde and reactive oxygen species contributing to liver damage. The enzyme is also associated with the development of certain cancers as its metabolism of procarcinogens can produce carcinogenic metabolites. Other related cytochrome P450 enzymes such as CYP1A2 share pathways involved in carcinogen activation highlighting an interconnected network contributing to disease progression.
