Effect
of the PC, PC:1, and PC:4 lipid
bilayers on catalytic triad (CT) dynamics. Scattered plots for CT
residues between the Ser195-His57 Cβ-atom and between the Asp102-His57
Cβ-atom obtained from a 40 ns simulation of flTF-FVIIa in the
(A) PC-, (B) PC:1-, and (C) PC:4-containing
phospholipid environments. The reference values for the CT residues
are 6.5 and 5.5 Å for S195:Cβ/H57:Cβ and D102:Cβ/H57:Cβ,
respectively. Localization of the CT residue is shown by the licorice
representation (right panel). Lipids 1 and 4 denote 1,2-dioleoyl-sn-glycero-3-phospho-L-serine
and 2,3-dioleoyl-sn-glycero-1-phospho-D-serine, respectively.
