Abstract:
:Thioredoxins are low-molecular-mass proteins that function as hydrogen carriers in DNA synthesis and in the transformation of sulfur metabolites. They also act as regulatory proteins in the light-dependent enzyme activation during photosynthesis. F-type thioredoxin from spinach chloroplasts, a monomeric protein of 113 amino acid residues, has been found to specifically activate fructose-1,6-bisphosphatase and other key enzymes of CO2 assimilation. It has been crystallized in the monoclinic system, space group P2(1) with a = 30.6 A, b = 63.1 A, c = 31.6 A and beta = 110.7 degrees. The crystals are suitable for X-ray diffraction studies.
