Figure 4. Close-up view of the protruding GH loop within the CP B domain of GFLV-F13 and GFLV-TD.

The conformation of the GH loop in GFLV-F13 (A) and GFLV-TD (B) are identical. The only difference is restricted to the presence of additional electron density corresponding to the Asp²⁹⁷ side chain in GFLV-TD in (B, star). 2Fo-Fc electron density maps are contoured at 1.2 σ.
