Molecular imprint of enzyme active site by camel nanobodies: rapid and efficient approach to produce abzymes with alliinase activity.
Screening of inhibitory Ab1 antibodies is a critical step for producing catalytic antibodies in the anti-idiotypic approach. However, the incompatible surface of the active site of the enzyme and the antigen-binding site of heterotetrameric conventional antibodies become the limiting step. Because camelid-derived nanobodies possess the potential to preferentially bind to the active site of enzy...
متن کاملMechanism-Based Studies of the Active Site-Directed Inhibition and Activation of Enzyme Transketolase
Derivatives of phenyl-keto butenoic acids have been reported to be inhibitors of pyruvate decarboxylase, (PDC). The inhibition of transketolase, a thiamine requiring enzyme such as PDF, by meta nitrophenyl derivative of 2-oxo-3-butenoic acid (MNPB) is reported here. These studies indicate that the inhibitor binds to the enzyme at the active site. A two-step inhibition was observed, first th...
متن کاملMolecular modelling and site-directed mutagenesis of the active site of endothelin-converting enzyme.
Mammalian endothelin-converting enzyme is a membrane-bound metalloprotease; its C-terminal domain contains sequence motifs characteristic of zinc metalloproteases. We examined residues expected from molecular modelling to be important for substrate binding using selectively mutated recombinant rat ECE-1alpha expressed in CHO cells. A conserved N-A-Ar-Ar (Ar = aromatic) motif is likely to be imp...
متن کاملLow dielectric response in enzyme active site.
The kinetics of charge transfer depend crucially on the dielectric reorganization of the medium. In enzymatic reactions that involve charge transfer, atomic dielectric response of the active site and of its surroundings determines the efficiency of the protein as a catalyst. We report direct spectroscopic measurements of the reorganization energy associated with the dielectric response in the a...
متن کاملMetric learning for enzyme active-site search
MOTIVATION Finding functionally analogous enzymes based on the local structures of active sites is an important problem. Conventional methods use templates of local structures to search for analogous sites, but their performance depends on the selection of atoms for inclusion in the templates. RESULTS The automatic selection of atoms so that site matches can be discriminated from mismatches. ...
