Definition

Target type: molecularfunction

Catalysis of the hydrolysis of a fatty acid amide to yield a fatty acid. [PMID:15952893]

Fatty acid amide hydrolase (FAAH) is an enzyme responsible for the hydrolysis of fatty acid amides, particularly anandamide (AEA), a neurotransmitter involved in the endocannabinoid system. FAAH catalyzes the breakdown of anandamide into arachidonic acid and ethanolamine, terminating its signaling activity. This enzymatic activity is crucial for regulating the levels of anandamide in the body, influencing a wide range of physiological processes. The molecular function of FAAH involves the following steps:

1. Binding of the substrate: FAAH interacts with the anandamide molecule, accommodating it within its active site.
2. Hydrolysis reaction: The enzyme utilizes a water molecule to cleave the amide bond between the fatty acid and the ethanolamine moiety of anandamide.
3. Product release: The reaction yields arachidonic acid and ethanolamine, which are released from the enzyme.

FAAH's activity plays a significant role in regulating pain perception, appetite, mood, memory, and inflammation. By breaking down anandamide, FAAH prevents its accumulation and associated effects. Its activity is also influenced by various factors, including genetic variations, environmental exposures, and disease states.

In summary, FAAH's molecular function is crucial for the regulation of anandamide signaling, impacting numerous physiological functions through its catalytic hydrolysis of anandamide.'
