The Transfer of the Ferredoxin Gene From the Chloroplast to the Nuclear Genome Is Ancient Within the Paraphyletic Genus Thalassiosira

Frontiers in Microbiology, 2020
Ferredoxins are iron–sulfur proteins essential for a wide range of organisms because they are an electron transfer mediator involved in multiple metabolic pathways. In phytoplankton, these proteins are active in the mature chloroplasts, but the petF gene,

Unique flexibility in energy metabolism allows mycobacteria to combat starvation and hypoxia. [PDF]

PLoS ONE, 2010
Mycobacteria are a group of obligate aerobes that require oxygen for growth, but paradoxically have the ability to survive and metabolize under hypoxia. The mechanisms responsible for this metabolic plasticity are unknown.

Adrenodoxin—A versatile ferredoxin [PDF]

IUBMB Life, 2012
AbstractMammalian adrenodoxin (Adx) has been known for many years as an essential electron mediator in mitochondrial cytochrome P450 systems. Because of its ability to support several cytochrome P450 enzymes, it is involved not only in adrenal steroid hormone biosynthesis but also in vitamin D and bile acid metabolism.

Automatically Defining Protein Words for Diverse Functional Predictions Based on Attention Analysis of a Protein Language Model

Advanced Science, EarlyView.
Understanding protein sequence–function relationships remains challenging due to poorly defined motifs and limited residue‐level annotations. An annotation‐agnostic framework is introduced that segments protein sequences into “protein words” using attention patterns from protein language models.

Heterogeneity of adrenocortical ferredoxin [PDF]

FEBS Letters, 1986
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

Elektrochemischer Schutz von Cyanobakterienzellen vor molekularem Sauerstoff ermöglicht nachhaltige PhotoH2‐Produktion

Angewandte Chemie, EarlyView.
Photosynthetische Mikroorganismen können zur lichtgetriebenen H2‐Entwicklung genutzt werden. Eine Einschränkung ist jedoch die damit verbundene Bildung von molekularem Sauerstoff als Nebenprodukt der Photosynthese, der die Aktivität des Biokatalysators für die H2‐Produktion, d. h. die Hydrogenase, inhibiert.

Electrochemical Protection of Cyanobacterial Cells from Molecular Oxygen Enables Sustained PhotoH2 Production

Angewandte Chemie International Edition, EarlyView.
Photosynthetic microorganisms can be used to perform H2 evolution driven by light. However, a crucial limitationlies in the associated generation of molecular oxygen as a by‐product of photosynthesis, which compromises the activity of the biocatalyst performing H2 production, i.e., the hydrogenase.

Influence of Zn2+ and Oxygen Supply on Malic Acid Production and Growth of Aspergillus oryzae

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Malic acid is a valuable platform chemical traditionally derived from fossil‐based resources. Microbial cultivation with Aspergillus oryzae offers a sustainable alternative based on renewable feedstocks. In this study, a well‐established minimal medium for malic acid production, commonly used in previous research to ensure reproducibility, was

Biomaterial design strategies for enhancing mitochondrial transplantation therapy

BMEMat, EarlyView.
Biomaterials to facilitate mitochondrial transplantation therapy: biomaterials as barriers to protect mitochondria from pathophysiological microenvironments, like osmotic stress caused by the excessive concentration of calcium ion, reactive oxygen species, and advanced glycation end products; biomaterials integrating with biochemical cues to improve ...
