Trends Biotechnol
. 2024 Dec;
43(3):647-672.
PMID: 39638703
Biogenic waste-derived feedstocks for production of fuels, chemicals, and materials offer great potential supporting the transition to net-zero and greater circularity. However, such feedstocks are heterogeneous and subject to geographical...

. 2023 Jul;
299(9):105086.
PMID: 37495113
Reductive dehalogenases are corrinoid and iron-sulfur cluster-containing enzymes that catalyze the reductive removal of a halogen atom. The oxygen-sensitive and membrane-associated nature of the respiratory reductive dehalogenases has hindered their...
