Ferredoxin containing bacteriocins suggest a novel mechanism of iron uptake in Pectobacterium spp.

PLoS ONE, 2012
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. Two sequenced strains of the phytopathogenic bacterium Pectobacterium carotovorum

Microbial Community Dynamics in Marine Water: Influence of Hydrocarbon Type and Exposure Time

Environmental Toxicology, EarlyView.
ABSTRACT Marine environments are frequently impacted by petroleum‐derived hydrocarbons, which pose ecological risks because of their toxic, mutagenic, and carcinogenic potential. Microorganisms play a crucial role in hydrocarbon degradation, and understanding the influence of time and hydrocarbon type on microbial dynamics helps improve bioremediation ...

Influence of heme and pH on the oligomeric states of Brucella melitensis bacterioferritin

Acta Crystallographica Section D, EarlyView.
The oligomerization of B. melitensis bacterioferritin (BmBfr) was studied using X‐ray crystallography, size‐exclusion chromatography and thermal shift analysis. These techniques allowed the characterization of both apo and holo BmBfr, highlighting the impact of heme and pH on the oligomerization mechanism.Bacterioferritin from Brucella melitensis ...

The Primary Structure of the Clostridium tartarivorum Ferredoxin, a Heat-stable Ferredoxin

Journal of Biological Chemistry, 1971
The amino acid sequence of the Clostridium tartarivorum ferredoxin was determined to be: Ala-His-Ile-Ile-Thr-Asp-Glu-Cys-Ile-Ser-Cys-Gly-Ala-Cys-Ala-Ala-Glu-Cys-Pro-Val-Glu-Ala-Ile-His-Glu-Gly-Thr-Gly-Lys-Tyr-Gln-Val-Asp-Ala-Asp-Thr-Cys-Ile-Asp-Cys-Gly-Ala-Cys-Gln-Ala-Val-Cys-Pro-Thr-Gly-Ala-Val-Lys-Ala-Glu. The first 23 residues were determined in the

FDX1 Depletion Activates CD8+ T Cell Antitumor Immunity by Promoting DMBT1 Secretion in Cuproptosis of Colorectal Cancer

Cancer Science, EarlyView.
Elesclomol‐induced cuproptosis potently activates both innate and adaptive antitumor immunity, especially CD8+ T cell immunity. FDX1 serves as a central regulator of CD8+ T cell functionality through DMBT1 downregulation during cuproptosis in colorectal cancer.

The Primary Structure of the Clostridium thermosaccharolyticum Ferredoxin, a Heat-stable Ferredoxin

Journal of Biological Chemistry, 1973
Abstract The amino acid sequence of Clostridium thermosaccharolyticum ferredoxin was determined to be:[see PDF for sequence]. Compared to the heat-stable ferredoxin from Clostridium tartarivorum, only two differences in the sequence were noted. Glutamine-31 and glutamine-44 in C.

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen

The FEBS Journal, EarlyView.
Serpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,

Unraveling the active site cover of coproheme decarboxylase from Listeria monocytogenes

The FEBS Journal, EarlyView.
During heme biosynthesis in Gram‐positive bacteria, coproheme decarboxylase (ChdC) catalyzes the conversion of four‐propionate substrate coproheme to the two propionate product heme b. Its active site is universally covered by a flexible linking loop. This study identifies an important histidine residue, which stabilizes the loop in a ChdC homolog.

Daily Heat Stress Induces Donor‐Side Limitation of PSI Via Downregulation of the Cyt b6f Complex

Plant, Cell &Environment, EarlyView.
ABSTRACT The rapidly warming climate is driving increasingly frequent and intense heat waves worldwide, posing major challenges to plant metabolism and growth. Despite the central role of photosynthesis in plant growth, the effects of prolonged heat stress on the primary reactions of photosynthesis remain poorly understood.
