Figure 5.
The space-filling model of the catalytic domain of the 4-carboxyglutamic acid (Gla)–domainless APC–D-Phe-Pro-Arg chloromethylketone (PPACK) complex. The relative 3-dimensional locations of the basic residues of 3 surface loops 39, 60, and 70-80 are shown in cyan. Shown in red are 2 of the catalytic triad residues (His57 and Ser195).
