full_question: The formation of these structures can be predicted by the DiANNA software. PRDX4 contributes to the formation of these structures by removing excess hydrogen peroxide. The formation of ascorbate via DHAR is accompanied by the formation of one of these structures in the enzyme's second substrate. Ero1 (ee-ro-one) regenerates the activity of one protein which forms these structures; that protein contains four TRX domains, two of which contain the CXXC motif. RNase A contains 4 of these structures, which prefer to have dihedral angles near 90°. One of these structures exists in the oxidized, but not the reduced form of glutathione. DTT and beta-mercaptoethanol are used to cleave these structures, which are formed by PDI. Keratin is rich in these structures, which link together the heavy and light chains of antibodies. For 10 points, name these bonds in the tertiary structures of proteins which form between cysteine residues.
