Data collection, refinement and model building statistics of mLTC4S in complex with sulfate (apo-form), GSH and S-hexyl GSH.

aRmerge = ∑hkl∑i|Ii(hkl) – hkl)>|/∑hkl∑i|Ii(hkl)|, where Ii(hkl) is the intensity of the ith measurement of reflection hkl and hkl)> is the average intensity of this reflection.bR = ∑ ||Fobs|–|Fcalc||/∑ |Fobs|.cRfree[38] was monitored with 5% of the reflection data excluded from refinement.das determined by MolProbity.Values for the highest resolution shell are given in parentheses.
