Fig. 5From: Effects of two kinds of imidazolium-based ionic liquids on the characteristics of steroid-transformation Arthrobacter simplex The location and function of reduced protein. Subcellular localization of the reduced proteins of two kinds of ILs treated cells and control cells (no ILs treatment). a Reduced proteins of [PrMIm]BF4-treated cell. b  Reduced proteins of [PrMIm]PF6-treated cell. The reduced proteins were determined by LC–MS/MS analysis, and peptide mass fingerprint was searched in NCBIBack to article page
