Figure 7. Docking poses and activity pocket for SAM in the crystal structure of VEGFA (PBD ID: 1MKK). (A) The disulfide bridges between C61A-C104A of VEGFA. (B) Docking site of VEGFA crystal structure. (C and D) Important residues are labeled and shown as sticks to facilitate the localization of PFA or SAM on the active site region in VEGFA.
