N-acetylated peptides with D-Ala in position 3 or 4 as are good substrates as those containing L-Ala. Peptides with Pro in position 2 are inactive, and most of the peptides with Pro in the third position are very good substrates. Only the peptide acetyl-AAP gives 30% of the activity of acetyl-AAA, which is reduced to 1-2% if additional residues are present at the C-terminus, acety-AAPA or acetyl-AAPAA. The presence of a positive charge in position 2,3,4,5 and 6 gives strong reduction in hydrolase activity, varying with the charge's distance from the N-terminus from 9 to 15-20% of the rate obtained with the reference peptides without positive charges. Deprotonation of His at high pH generates excellent substrates, and removal of the positive charges of Lys by acetylation or succinylation give improved substrate quality. Long peptides with 10-29 residues, are poor substrates, especially when they contain positive charges and Pro

by hanging drop method. AAP crystallized with the product-like inhibitors Ac-Phe and Gly-Phe, as well as with the substrate Abz-GFEPF(NO2)RA. Mutant S445A crystallized with Abz-GFEPF(NO2)RA. Complexes belong to P212121. Crystal structures of AAPinhibitor complexes reveal the oxyanion-binding site and the specificities of the S1, S2 and S3 subsites. Substrate-binding site extends beyond the S2 subsite, being capable of binding peptides with a longer N-terminus. The S2 subsite displays a non-polar character. The S3 site reveals a hydrophobic region that does not form hydrogen bonds with the inhibitor P3 residue. The enzymeinhibitor complexes reveal that, upon ligand-binding, the S1 subsite undergoes significant conformational changes

construction of chimeras of a carboxylesterase (EC 3.1.1.1) from Archaeoglobus fulgidus and an acylpeptide hydrolase (EC 3.4.19.1) from Aeropyrum pernix K1. Their activities to hydrolyze 4-nitrophenyl esters (pNP) with different acyl chain lengths is explored. The chimeras inherit the thermophilic property of both parents. The substrate-binding domain is the dominant factor on enzyme substrate specificity, and the optimization of the newly formed domain interface is an important guarantee for successful domain swapping of proteins with low-sequence homology
