Abstract
An unconventional dehalogenase: An engineered variant (I64V/V106L) of the mouse cytokine macrophage migration inhibitory factor (MIF) promiscuously catalyzes the hydrolytic dehalogenation of the xenobiotic organohalogen trans-3-chloroacrylic acid to acetaldehyde. Although the dehalogenase activity of this MIF variant is quite low, it achieves an ~10(9) -fold rate enhancement, matching those of conventional enzymes acting on their natural substrates.
