The soluble C-terminal domain of YuaF was generated by cleaving off the malE part by digestion with thrombin. 遺伝子: yuaF / 発現宿主: ![]() ![]() |

The 100 structures with lowest target function in CYANA 2.0 were imported into AMBER 8, minimized and subjected to simulated annealing in vacuum with charges reduced to 20% of their original value. The final round of simulated annealing was carried out within a generalized-Born solvation model with full charges followed by energy minimization. Constraints from CYANA were translated into AMBER 8 format taking stereospecific assignments, pseudoatom corrections and NOE-averaging into account. | ||||||||||||||||||||||||
