FEBS Letters, 2005 The NuoF subunit, which harbors NADH‐binding site, of Escherichia coli NADH‐quinone oxidoreductase (NDH‐1) contains five conserved cysteine residues, four of which are predicted to ligate cluster N3. To determine this coordination, we overexpressed and purified the NuoF subunit and NuoF + E subcomplex in E. coli.

Ce‐Doped Lignin‐Based Nanozyme with Heat‐Activated Hydrolase Activity
Advanced Science, EarlyView.A novel Ce‐doped lignin‐based hydrolase nanozyme (Ce‐AL) is synthesized using Ce ions coordinated with aminated industrial lignin. The Ce‐AL effectively hydrolyzes phosphate ester bonds and protein amide bonds, maintain high activity at 100°C, and successfully fights bacteria biofilms.

A structural phylogeny for understanding 2-oxoacid oxidoreductase function [PDF]
, 2018 2-Oxoacid:ferredoxin oxidoreductases (OFORs) are essential enzymes in microbial one-carbon metabolism. They use thiamine pyrophosphate to reversibly cleave carbon-carbon bonds, generating low potential (~-500 mV) electrons. Crystallographic analysis of a
