Optimization of the expression of levansucrase L17 in recombinant E. coli

open access: yesBiotechnology & Biotechnological Equipment, 2018
Levansucrases synthesize levans and fructooligosaccharides, which are of interest in the food and pharmaceutical industry. Leuconostoc mesenteroides Lm 17 produces levansucrase of about 120 kDa. The encoding gene from this strain was cloned and expressed

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Nuclear Factor E2–Related Factor 2–Mediated Induction of NAD(P)H:Quinone Oxidoreductase 1 by 3,5-Dimethoxy-trans-stilbene

open access: yesJournal of Pharmacological Sciences, 2011
.: NAD(P)H:quinone oxidoreductase 1 (NQO1), a phase II enzyme, plays an important role in the detoxification or chemoprotection of carcinogens, and induction of this enzyme is a target for the prevention of carcinogenesis.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Expression optimization of recombinant cholesterol oxidase in Escherichia coli and its purification and characterization

open access: yesAMB Express, 2018
Cholesterol oxidase is a bacterial flavoenzyme which catalyzes oxidation and isomerization of cholesterol. This enzyme has a great commercial value because of its wide applications in cholesterol analysis of clinical samples, synthesis of steroid-derived

Enzyme Induction in Immature Glia.

open access: yesExperimental Biology and Medicine, 1965
ConclusionThis study clearly demonstrates that astrocytes of newborn rat brain display the morphologic and enzymatic changes of reactive gliosis in response to the appropriate stimulus. The absence of newborn glial response to simple penetrating wounds may be a result of ineffective liberation of an inducing agent present at low concentration.
