Reaction of the NAD(P)H:flavin oxidoreductase from Escherichia coli with NADPH and riboflavin: identification of intermediates [PDF]
Biochemistry, American Chemical Society, 1998, 37, pp.11879-87, 2014 Flavin reductase catalyzes the reduction of free flavins by NAD(P)H. As isolated, Escherichia coli flavin reductase does not contain any flavin prosthetic group but accommodates both the reduced pyridine nucleotide and the flavin substrate in a ternary complex prior to oxidoreduction.

Activation of 3-Mercaptopyruvate Sulfurtransferase by Glutaredoxin Reducing System
Biomolecules, 2020 Glutaredoxin (EC 1.15–1.21) is known as an oxidoreductase that protects cysteine residues within proteins against oxidative stress. Glutaredoxin catalyzes an electron transfer reaction that donates an electron to substrate proteins in the reducing system

A method for facile production of variable lymphocyte receptors using SHuffle Escherichia coli
Biotechnology Progress, EarlyView.Abstract Variable lymphocyte receptors (VLRs) are the antigen receptors of jawless vertebrates such as lamprey. VLRs are of growing biotechnological interest for their ability to bind certain antigenic targets with higher affinity than traditional immunoglobulins.

Biotechnology Progress, EarlyView.Abstract The production of disulfide‐containing recombinant proteins often requires refolding of inclusion bodies before purification. A pre‐refolding purification step is crucial for effective refolding because impurities in the inclusion bodies interfere with refolding and subsequent purification.
