Activity summary

NAT1 also known as arylamine N-acetyltransferase 1 serves as an important enzyme in acetylation reactions. This enzyme with a molecular mass of approximately 33 kDa catalyzes the transfer of acetyl groups to arylamines and other substrates such as hydrazines. By doing so NAT1 influences xenobiotic metabolism. The enzyme is expressed in various tissues most notably in the liver intestine and lung which aligns with its role in detoxifying and metabolizing drugs and carcinogens.

Biological function summary

NAT1 plays a significant role in detoxifying environmental toxins and carcinogens. The enzyme's activity contributes to the acetylation a phase II metabolic reaction which often converts lipophilic substrates into more hydrophilic products for excretion. NAT1 stands independently and does not form part of a larger complex. It shares functional similarities with other N-acetyltransferases but its substrate specificity can differ which influences its distinct biological role.

Pathways

NAT1 is intricately involved in metabolic and detoxification pathways. It participates in the biotransformation of various drugs and environmental carcinogens making it important for xenobiotic metabolism. NAT1 often interacts with cytochrome P450 enzymes during these processes which also contribute to the initial phase I oxidation reactions. The interplay between NAT1 and these detoxification pathways highlights the enzyme's contribution to reducing potential toxicities.

Associated diseases and disorders

NAT1 has associations with both cancer and hypersensitivity to certain drugs. Variations in NAT1 activity due to genetic polymorphisms can influence individual susceptibility to cancers particularly bladder cancer linked to arylamine exposure. Additionally its interaction with cytochrome P450 enzymes may also impact drug metabolism potentially leading to adverse drug reactions. Understanding NAT1 and its interactions help assess risks related to these diseases.
