Fig. 1. Superposition of the crystal structures of AtFKBP42^1-180 (blue), HsFKBP12 (grey) and AtFKBP13 (orange). Secondary structure elements of the canonical FKBP fold are numbered consecutively; β0 is an additional β-strand present in AtFKBP42^1-180. The FK506 molecule bound to HsFKBP12 is shown as stick model.
