3.4.19.1 | additional information | construction of mutant APE-DELTAEG by deletion of two residues E316 and G317, and of mutant APE-2G by inserted two Gly residues between residues L315 and E316 deleted residues F395 and V396. The catalytic activity of the APE-DELTAEG mutant toward 4-nitrophenyl butyrate (pNPC4) is 2.8fold more active compared to wild-type, whose preferred substrate is 4-nitrophenyl caprylate (pNPC8) | Aeropyrum pernix |
3.4.19.1 | additional information | construction of N-terminus deletion mutants DELTAN21 and DELTAN21-4 A, which can be obviously discriminated from the wild-type in terms of activity in various pH values. Mutant ST-4 A exhibits higher activity toward substrate Ac-Ala-Ala-Ala at 70°C compared with the wild-type enzyme. ST-4 A enzymatic activity is 2fold more active than wild-type at 95°C and ST-6 A enzymatic activity is 1.7fold more active than wild-type at 95°C. Construction of mutants ST-DELTAGL by deletion of residues G332 and L333, of mutant ST-2 A by insertion of four Ala residues between residues G331 and G332, of mutant ST-6 A by removal of N-terminal 21 residues and linker insertion with four Ala residues between residues G331 and G332, and of mutant DELTAN21, overview | Sulfurisphaera tokodaii |

3.4.19.1 | More | APH family is composed of a beta-propeller domain in N-terminus and a catalytic domain in C-terminus. These domains are structurally connected by bridge regions. One is the N-terminus region that stretches into the C-terminal catalytic domain. The other is the linker that directly connects the beta-propeller domain to the catalytic domain. N-terminus region forms a unique alpha-helix 1 (alpha1), which deviates from the beta-propeller domain. Nevertheless, it connects with the surface of the catalytic domain. The structure of alpha1 is conserved and affects conformational flexibility | Aeropyrum pernix |
