Ferredoxin containing bacteriocins suggest a novel mechanism of iron uptake in Pectobacterium spp [PDF]
In order to kill competing strains of the same or closely related bacterial species, many bacteria produce potent narrow-spectrum protein antibiotics known as bacteriocins.

Ferredoxin and ferredoxin–heme maquettes [PDF]
A 16-amino acid residue peptide derived from a consensus motif of natural ferredoxins incorporates a tetranuclear iron sulfur cluster under physiological conditions. Successful assembly of the [4Fe–4S] 2+/1+ cluster within a monomeric peptide was demonstrated using size exclusion chromatography, UV-visible ...

Plant type ferredoxins and ferredoxin‐dependent metabolism [PDF]
Ferredoxin (Fd) are small [Fe‐S] cluster containing proteins, which act as the first soluble acceptors of electrons on the stromal side of the chloroplast electron transport chain. In addition to their primary function in photosynthesis, Fds are also involved in a number of other essential metabolic reactions, including biosynthesis of chlorophyll ...

The interaction of ferredoxin‐linked sulfite reductase with ferredoxin [PDF]
Spinach sulfite reductase has been shown to co‐migrate during gel filtration chromatography at low ionic strength with spinach ferredoxin. No co‐migration was observed at high ionic strength. These results indicate that the two proteins form a high‐affinity, electrostatically stabilized complex, as had previously been demonstrated for three other ...

Heterogeneity of adrenocortical ferredoxin [PDF]
Bovine adrenocortical ferredoxin (adreno‐ferredoxin) was purified from adrenocortical mitochondria by an improved method that included hydrophobic chromatography on Toyopearl gels. The purified ferredoxin was electrophoretically homogeneous. It was further separated into five fractions by hydrophobic chromatography on a TSK‐gel phenyl‐5PW column with a

Structure of the atypical bacteriocin pectocin M2 implies a novel mechanism of protein uptake [PDF]
The colicin-like bacteriocins are potent protein antibiotics that have evolved to efficiently cross the outer membrane of Gram-negative bacteria by parasitizing nutrient uptake systems.

CO2-Induced Transcriptional Reorganization: Molecular Basis of Capnophillic Lactic Fermentation in Thermotoga neapolitana [PDF]
Capnophilic lactic fermentation (CLF) is a novel anaplerotic pathway able to convert sugars to lactic acid (LA) and hydrogen using CO2 as carbon enhancer in the hyperthermophilic bacterium Thermotoga neapolitana.

A haloarchaeal ferredoxin electron donor that plays an essential role in nitrate assimilation [PDF]
In the absence of ammonium, many organisms, including the halophilic archaeon Haloferax volcanii DS2 (DM3757), may assimilate inorganic nitrogen from nitrate or nitrite, using a ferredoxin-dependent assimilatory NO3-/NO2- reductase pathway.

Immunological comparison of ferredoxins [PDF]
1. Introduction The biological significance of ferredoxins in various processes, and the increasing number of them that have been isolated and characterized from bacterial, plant and animal systems, have stimulated investigations on the physico-chemical properties of these proteins [ 1,2].

The genetic basis of energy conservation in the sulfate-reducing bacterium Desulfovibrio alaskensis G20. [PDF]
Sulfate-reducing bacteria play major roles in the global carbon and sulfur cycles, but it remains unclear how reducing sulfate yields energy. To determine the genetic basis of energy conservation, we measured the fitness of thousands of pooled mutants of
