Genomic determinants of organohalide-respiration in Geobacter lovleyi, an unusual member of the Geobacteraceae

open access: yesBMC Genomics, 2012
Background Geobacter lovleyi is a unique member of the Geobacteraceae because strains of this species share the ability to couple tetrachloroethene (PCE) reductive dechlorination to cis-1,2-dichloroethene (cis-DCE) with energy conservation and growth (i ...

Cobalamin production by Lactobacillus coryniformis: Biochemical identification of the synthetized corrinoid and genomic analysis of the biosynthetic cluster [PDF]

open access: yes, 2016
Background: Despite the fact that most vitamins are present in a variety of foods, malnutrition, unbalanced diets or insufficient intake of foods are still the cause of vitamin deficiencies in humans in some countries.

Pseudovitamin B(12) is the corrinoid produced by Lactobacillus reuteri CRL 1098 under anaerobic conditions [PDF]

open access: yes, 2007
We have reported previously on the ability of Lactobacillus reuteri to produce a compound with vitamin B-12 activity. Here we report on the chemical characterisation of this corrinoid-like molecule.

Genomic potential for mercury biotransformation in marine sediments across marginal slope to hadal zone

open access: yesNature Communications
Mercury accumulates in the deep sea, but its ecological impact on deep-sea ecosystems remains poorly understood. We conduct an analysis of 32 sediment cores, comprising 101 layers for the study of metagenomes, and additional 41 global reference sediment ...

Ecology of Organohalide-Respiring \u3ci\u3eDehalococcoides mccartyi\u3c/i\u3e: Corrinoid Cofactor-Related Community Interactions and Controls over Strain Selection [PDF]

open access: yes, 2016
Organohalides such as tetrachloroethene (PCE) and trichloroethene (TCE) are among the most prevalent toxic groundwater contaminants. Remediation of organohalide-contaminated sites has high priority, and efficient and cost-effective remedies are needed to

Control of Metal-Catalyzed Reactions by Organic Ligands: From Corrinoid and Porphinoid Metal Complexes to Tailor-Made Catalysts for Asymmetric Synthesis [PDF]

open access: yes, 1990
Corrinoid and porphinoid metal complexes playa fundamental role in nature as catalysts for a variety of biochemical transformations. The properties of the metal ion in these complexes are strongly influenced by the macrocyclic ligand.

Identification of purinyl-cobamide as a novel corrinoid cofactor of tetrachloroethene reductive dehalogenases in \u3ci\u3eDesulfitobacterium\u3c/i\u3e spp. [PDF]

open access: yes, 2015
Corrinoids (e.g. vitamin B12) [cyanocobalamin] are a group of structurally similar, cobaltcontaining tetrapyrrole compounds involved in a number of important biochemical reactions.

The Vitamin Profile of Edible and Medicinal Mushrooms: Bioactive Potential, Preventive Health Significance, and Applied Perspectives

open access: yesApplied Sciences
Edible and medicinal mushrooms are widely studied for their bioactive compounds, yet their role as sources of essential vitamins remains inadequately defined and often overestimated.

Corrinoid-mediated reduction of tetrachloroethene, trichloroethene, and trichlorofluoroethene in homogeneous aqueous solution: reaction kinetics and reaction mechanisms

open access: yes, 1997
It is shown that in homogeneous aqueous solution containing titanium(III) citrate or titanium(III)-NTA as bulk electron donor, cobalamin, cobinamide, and cobamide are effective electron transfer mediators for the reduction of tetrachloroethene (PCE ...

Site-specific incorporation of 19F-nuclei at protein C-terminus to probe allosteric conformational transitions of metalloproteins

open access: yesCommunications Biology
Allosteric conformational change is an important paradigm in the regulation of protein function, which is typically triggered by the binding of small cofactors, metal ions or protein partners.
