Expression and characterization of the Escherichia coli fdo locus and a possible physiological role for aerobic formate dehydrogenase
TLDR
Aerobically expressed FDH-Z and NAR-Z enzymes were shown to reduce nitrate at the expense of formate under anaerobic conditions, suggesting that this pathway would allow the cell to respond quickly to anaerobiosis.
Suppression of Escherichia coli formate hydrogenlyase activity by trimethylamine N-oxide is due to drainage of the inducer formate.
TLDR
Results strongly suggest that formate-dependent reduction of TMAO via FDH-N and TOR reduces the amount of formate available for induction of the formate hydrogenlyase pathway.
Topological Analysis of the Aerobic Membrane-Bound Formate Dehydrogenase of Escherichia coli
TLDR
It is suggested that the alphabeta catalytic dimer is located in the cytoplasm, with a C-terminal anchor for beta protruding into the periplasm, in contrast to previously reported predictions from sequence analysis.
The hydrogenases and formate dehydrogenases ofEscherichia coli
TLDR
The identification of the structural genes encoding the formate dehydrogenase and hydrogenase isoenzymes has enabled a detailed dissection of how their expression is coordinated to the metabolic requirement for their products, and a picture is emerging of the extremely complex and involved path of events leading to the regulated synthesis, processing and assembly of catalytically active formate dehydrationases and hydrogenases.
Identification of the formate dehydrogenases and genetic determinants of formate-dependent nitrite reduction by Escherichia coli K12.
TLDR
It is concluded that all three of the known formate dehydrogenases of E. coli can contribute to the transfer of electrons from formate to the Nrf pathway.
The Aerobic and Anaerobic Respiratory Chain of Escherichia coli and Salmonella enterica: Enzymes and Energetics.
TLDR
The energetics of the individual redox reactions and the respiratory chains is described and related to the H+/2e- ratios.

TLDR
Results indicate that the formate substrate does not coordinate directly to Mo when it enters the oxidised active site of the FDH, but instead resides in the second coordination sphere, which is supported by recent experimental studies.
Molybdenum and tungsten-dependent formate dehydrogenases
TLDR
This review will highlight the present knowledge about the diverse physiological roles of FDH in prokaryotes, their modular structural organisation and active site structures and the mechanistic strategies followed to accomplish the formate oxidation.

Structural genes for nitrate-inducible formate dehydrogenase in Escherichia coli K-12.
TLDR
It is concluded that regulation of fdnGHI and narGHJI expression is mediated through common pathways.
Biochemical and immunological evidence for a second nitrate reductase in Escherichia coli K12.
TLDR
It is shown that E. coli has two types of nitrate reductase, one of which is a membrane-bound molybdoenzyme able to couple formate oxidation with nitrate reduction and another which shares some similarities as well as differences with the known enzyme.
Nitrate Reductase Complex of Escherichia coli K-12: Participation of Specific Formate Dehydrogenase and Cytochrome b1 Components in Nitrate Reduction
TLDR
It is concluded that nitrate reduction in E. coli is mediated by the sequential operation of a specific formate dehydrogenase, two specific cytochrome b(1) components, and nitrate reductase.
Formation of the formate-nitrate electron transport pathway from inactive components in Escherichia coli
TLDR
Activation by molybdate results in molecular changes which include the reassociation of cytochrome b1 with formate dehydrogenase and restoration of both enzymes to their original electrophoretic mobilities.
Mutants of Escherichia coli specifically deficient in respiratory formate dehydrogenase activity.
TLDR
Construction of merodiploid strains harbouring various combinations of the mutated alleles, fdhE on the episome and fdhD on the chromosome, led to the restoration of FDH-PMS activity by complementation of the products encoded by the respective wild-type alleles.
The organization of formate dehydrogenase in the cytoplasmic membrane of Escherichia coli.
TLDR
A procedure involving agglutination with specific antibodies is described which appears to fractionate membrane vesicles of mixed orientation into two populations, one with the same membrane orientation as that of spheroplasts and the other opposite orientation.
Formation of active heterologous nitrate reductases between nitrate reductases A and Z of Escherichia coli
TLDR
Two nitrate reductases, NRA and NRZ, are present in Escherichia coli and it is demonstrated that the translation of the subunits and their assembly are not coupled processes, since subunits produced concomitantly but independently can meet efficiently and associate to form active enzymes.
