additional information | the thermodynamics of formation of a complex of Arabidopsis thaliana O-acetylserine sulfhydrylase and the C-terminal ligand of AtSAT (C10 peptide) as a function of temperature and salt concentration using fluorescence spectroscopy and isothermal titration calorimetry is analysed. Results show that the C-terminus of AtSAT provides the major contribution to the total binding energy in the plant cysteine synthase complex. The C10 peptide binds to the O-acetylserine sulfhydrylase homodimer in a 2:1 complex. Interaction between AtOASS and the C10 peptide is tight (Kd: 5-100 nM) over a range of temperatures (10-35°C) and NaCl concentrations (0.02-1.3 M) | Arabidopsis thaliana |
