A dual-reactive compound is added to form the 14-3-3γ/ERRγ/5 ternary complex. WebMaleimides are thiol-reactive reagents that can be conjugated to sulfhydryl (thiol) groups. The primary reactive species for protein thiol-conjugation are the sulfhydryl groups of cysteine residues. Cysteine residues can form disulfide bridges via oxidative dimerization, which helps stabilize protein ternary structures.
