β1 domain-swapped structure of m-cGrx1. (a) The domain-swapped m-cGrx1 molecules (subunits B and C) are shown in red and orange and the disulfide dimeric m-cGrx1 molecules (subunits A and D) are shown in gray and black. The red arrow indicates the intermolecular disulfide bridge between subunits A and C. (b) The hinge loop is located between β1 and α1. (c) Structural comparison of d-cGrx1 and β1 domain-swapped m-cGrx1. The β1 domain-swapped m-cGrx1 (orange) reveals that the tertiary structure is unwound compared with that of d-cGrx1 (beige) and the hinge loop is located between α1 and β1. The α1 helix is partially unfolded.
