Catalysis and stability of triosephosphate isomerase from Trypanosoma brucei with different residues at position 14 of the dimer interface. Characterization of a catalytically competent monomeric enzyme.

Abstract excerpt

In homodimeric triosephosphate isomerase from Trypanosoma brucei (TbTIM), cysteine 14 of each the two subunits forms part of the dimer interface. This residue is central for the catalysis and stability of TbTIM. Cys14 was changed to the other 19 amino acids to determine the characteristics that the residue must have to yield catalytically competent stable enzymes. C14A, C14S, C14P, C14T, and C14V TbTIMs were...
