3.4.19.1	additional information	the catalytic triad is composed by catalytic residues Ser566, Asp654, and His686	753727	
3.4.19.1	additional information	the closed form of the enzyme is catalytically active, while opening deactivates the catalytic triad. Molecular-dynamics simulations are used to investigate the structure of the complexes formed with longer peptide substrates showing that their binding within the large crevice of the closed form of ApAAP leaves the enzyme structure unperturbed. Their accessing the binding site seems more probable when assisted by opening of the enzyme. Thus, the open form of ApAAP corresponds to a scavenger of possible substrates, the actual cleavage of which only takes place if the enzyme is able to re-close. Structure analysis, detailed overview	-, 752387	
3.4.19.1	additional information	the three-dimensional structure of the psychrophilic acyl aminoacyl peptidase from Sporosarcina psychrophila (SpAAP) highlights adaptive molecular changes resulting in a fine-tuned trade-off between flexibility and stability. A feature of SpAAP cold adaptation is the enlargement of the tunnel connecting the exterior of the protein with the active site. Such a wide channel might compensate for the reduced molecular motions occurring in the cold and allow easy and direct access of substrates to the catalytic site, rendering transient movements between domains unnecessary. Thus, cold-adapted SpAAP has developed a molecular strategy unique within this group of proteins: it is able to enhance the flexibility of each functional unit while still preserving sufficient stability. The Ser-Asp-His catalytic triad in SpAAP (Ser458, Asp540 and His572) matches that of the canonical alpha/beta hydrolase fold	753553

3.4.19.1	physiological function	enzyme APEH is a component of the cellular response to DNA damage. APEH is primarily localised in the cytoplasm, but a subfraction of the enzyme is sequestered at sites of nuclear damage following UVA irradiation or following oxidative stress. Localization of APEH at sites of nuclear damage is mediated by direct interaction with XRCC1, a scaffold protein that accelerates the repair of DNA single-strand breaks. APEH interacts with the amino-terminal domain of XRCC1, and APEH facilitates both single-strand break repair and cell survival following exposure to H2O2 in human cells	753398
