The Na+ cycle in Acetobacterium woodii: identification and characterization of a Na+ translocating F1F0-ATPase with a mixed oligomer of 8 and 16 kDa proteolipids [PDF]
, 2001 The homoacetogenic bacterium Acetobacterium woodii relies on a sodium ion current across its cytoplasmic membrane for energy-dependent reactions. The sodium ion potential is established by a yet to be identified primary, electrogenic pump connected to ...

Formation of cobalt-free corrinoids in Rhodopseudomonas spheroides.
Journal of Nutritional Science and Vitaminology, 1977 Co-free corrinoids (CFCs) were found in the cells of Rhodopseudomonas spheroides grown without cobalt salt. A predominant fraction of three CFCs on paper-electrophoregram was further purified, and investigated physico-chemically as well as microbiologically in comparison with that isolated by Toohey from Chromatium.

The Ligand Substitution Reactions of Hydrophobic Vitamin B12 Derivatives. Reaction of Cobyric Acid Heptapropyl Ester with Heterocyclic N-donor Ligands [PDF]
, 2015 The hydrophobic cobyrinic acid heptapropyl ester corrinoids XCbs-Pr (axial ligand X=CN–, SO32–, CH3– and CH3CH2–) have been prepared from vitamin B12 by hydrolysis of the amide side chains and their conversion to propyl esters. Both the position of the γ-

Corrinoid-Metabolismus in Sporomusa ovata H1
, 2012 Sporomusa ovata H1 produces acetic acid from methanol plus CO2. Two vitamin B12 derivates are involved in this pathway: p-cresolylcobamide and phenolylcobamide. The biosynthesis of these corrinoids involves two unusual reactions: cleavage of tyrosine into phenol and p-cresol and O-glycosidic ligation of these aromatics to ribose.
