3.1.6.31 Borchert, T.V., Abagyan, R.A., Jaenicke, R., and Wierenga, R.K. (1994). Design, creation, and characterization of a stable, monomeric triosephosphate isomerase. Proc. Natl. Acad. Sci. USA, 91, 1515-1518

Protein engineering on trypanosomal triosephosphate isomerase (TIM) converted this oligomeric enzyme into a stable, monomeric protein that is enzymatically active. Wild-type TIM consists of two identical subunits that form a very tight dimer involving interactions of 32 residues of each subunit. By replacing 15 residues of the major interface loop by another 8-residue fragment, a variant was constructed that is a stable and monomeric protein with TIM activity. The length, sequence, and conformation of the designed fragment were suggested by extensive modeling.
