Cobalamin Protection against Oxidative Stress in the Acidophilic Iron-oxidizing Bacterium Leptospirillum Group II CF-1

open access: yesFrontiers in Microbiology, 2016
Members of the genus Leptospirillum are aerobic iron-oxidizing bacteria belonging to the phylum Nitrospira. They are important members of microbial communities that catalyze the biomining of sulfidic ores, thereby solubilizing metal ions.

Unveiling the significance of prokaryotic composition from ferromanganese crusts regarding the interlink between cobalt and vitamin B12 in deep-sea ecosystems [PDF]

open access: yesFrontiers in Microbiology
The intricate relationship between prokaryotic vitamin B12 (cobalamin) producers and metazoans in deep-sea ecosystems, particularly within ferromanganese crusts and polymetallic nodules, is critical for understanding oceanic biogeochemical cycling of ...

Sinorhizobium meliloti Requires a Cobalamin-Dependent Ribonucleotide Reductase for Symbiosis With Its Plant Host [PDF]

open access: yesMolecular Plant-Microbe Interactions, 2010
Vitamin B12 (cobalamin) is a critical cofactor for animals and protists, yet its biosynthesis is limited to prokaryotes. We previously showed that the symbiotic nitrogen-fixing alphaproteobacterium Sinorhizobium meliloti requires cobalamin to establish a

Disorder of intracellular cobalamin metabolism: Importance of rapid diagnostic illustrated by a case report of early-onset methylmalonic aciduria and homocystinuria, cobalamin C type [PDF]

open access: yesHeliyon
Methylmalonic aciduria and homocystinuria, cobalamin C type (cblC), constitute the most common inborn error of intracellular cobalamin metabolism. Here, we report the case of a 6-month-old child, presenting severe subacute neurological decline associated
