the higher stability of the indole-3-glycerol phosphate synthase from Sulfolobus solfataricus compared to indole-3-glycerol phosphate synthase from Escherichia coli seems to be the result of several improved interactions. These include a larger number of salt bridges, stabilization of alpha helices and strengthening of both polypeptide chain termini and solvent-exposed loops |
