==Summary==

===Protein Function ===
NAAA must operate under acidic conditions (pH ~4.5), and is completely inactivated at a pH of 8. Selective inhibitors of NAAA are ester and amide compounds, such as N-cyclohexanecarbonylpentadecylamine. NAAA is cleaved proteolytically at residue Cys126. NAAA cleaves C-N non-peptide bonds in linear amides, particularly ethanolamides. Its mechanism is quite similar to that of AC, which is further supported by AC's ability to cleave N-acylethanolamines (NAEs), albeit at far lower rates and with different specificities. While mechanistic details are not very well known, catalytic activity of NAAA is thought to be activated by Cys126 and Asp145. 
Fatty acid ethanolamines (FAEs) perform several physiological functions, most notably serving as messengers for pain and inflammation. NAAA's are found primarily in the lysosomal compartment of macrophages, in line with most inflammation-related proteins. They perform FAE hydrolysis, the final step in the signaling cascade for pain and inflammation, yielding an ethanolamine and a fatty acid. While it processes the cleavage of many different substrates, NAAA is most active with the substrate N-palmitoylethanolamine, suggesting that this is one of the key messengers of pain.
