Crystal structure of the tetrachloroethene reductive dehalogenase from Sulfurospirillum multivoransCrystal structure of the tetrachloroethene reductive dehalogenase from Sulfurospirillum multivorans
Structural highlights
Publication Abstract from PubMedOrganohalide-respiring microorganisms can use a variety of persistent pollutants including trichloroethene (TCE) as terminal electron acceptors. The final two-electron transfer step in organohalide respiration is catalyzed by reductive dehalogenases. Here we report the x-ray crystal structure of PceA, an archetypal dehalogenase from Sulfurospirillum multivorans, as well as structures of PceA in complex with TCE and product analogs. The active site harbors a deeply buried norpseudo-B12 cofactor within a nitroreductase fold, also found in a mammalian B12 chaperone. The structures of PceA reveal how a cobalamin supports a reductive haloelimination exploiting a conserved B12-binding scaffold capped by a highly variable substrate-capturing region. Structural basis for organohalide respiration.,Bommer M, Kunze C, Fesseler J, Schubert T, Diekert G, Dobbek H Science. 2014 Oct 2. pii: 1258118.
