The coordinate bonding interaction between His and Zn2 +in T1 lipase (PDB code: 1JI3). (A) The location of His81, His87, and Zn2+ in the T1 lipase structure. (B) The coordinated bonds between His81 and Zn2+, and between His87 and Zn2+. The coordinate bond lengths of His81–Zn2+ and His87–Zn2+ are 2.12 Å and 1.99 Å, respectively, very close to the optimized distance (1.9519 Å).
