DJ-1 structures with cysteines in different
oxidation states (PDB
entries 1SOA, 4RKW, 4P34, and 2R1T), with the dimeric
interface region (residues 38–70) colored green. The cysteines
in the structure are shown in ball-and-stick representation labeled
with their respective residue numbers. The regions enclosed in the
dashed box containing Cys106 in different oxidation states (-SH, -SOH,
and -SOOH) are enlarged in panels B–D. The positions associated
with familial mutations are colored red on the cartoon representation
with their residue numbers shown. Cys53 can undergo dopamine quinone
conjugation (inset in the top right corner of panel A).
