Polytetrafluoroethylene 66-69 cytochrome c, somatic Equus caballus 12-24 7729510-3 1995 On the other hand, in buffer only and in the absence of TFE, cytochrome c is digested by thermolysin to numerous small peptides. Polytetrafluoroethylene 56-59 cytochrome c, somatic Equus caballus 61-73 7729510-5 1995 It is proposed that the highly helical secondary structure acquired by cytochrome c when dissolved in aqueous TFE hampers binding and adaptation of the protein substrate at the active site of the protease and that peptide bond fission occurs at flexible chain segments characterized by a low alpha-helix propensity. Polytetrafluoroethylene 110-113 cytochrome c, somatic Equus caballus 71-83
