Zur Struktur rhodiumhaltiger Corrinoide

Liebigs Annalen der Chemie, 1980
AbstractDurch Umsetzung von Hydrogenobyrinsäure‐a,c‐diamid (1) mit [Rh(CO)2Cl]2 in Eisessig/Ethanol (1:1; Vol.: Vol.) erhält man als Hauptprodukt Rhodibyrinsäure‐a,c‐diamid 2. Die Identität von 2 wird durch Röntgenstrukturanalyse bestätigt. Veresterung von 2 mit Methanol/Schwefelsäure führt neben Rhodibyrinsäure‐pentamethylester‐a,c‐diamid 3a zu den ...

Quantification of corrinoids in methanogenic bacteria

Current Microbiology, 1980
Corrinoids in several diverse species of methanogens were quantified by a bioassay utilizingEscherichia coli 113-3, a corrinoid auxotroph. All five species examined contained >0.65 nmol corrinoid/mg dry cells when grown on H2/CO2 as carbon and energy source.

Corrinoid and thiol dependent threonine decarboxylation

Biochemical and Biophysical Research Communications, 1976
Summary A novel system for the decarboxylation of L-threonine requiring the presence of certain aquocorrinoids, preferably diaquocobyric acid, and of a thiol is described. The reaction shows a marked optimum at a pH value of about 8. Other L-amino acids, with the exception of L-serine, are much less reactive. Optical data point to a ligand attachment

Analysis of corrinoids in ovine tissues

Biomedical Chromatography, 2005
AbstractCorrinoids from various ovine tissue samples (liver, blood, small intestinal fluid and faeces) were analysed using a combination of high‐performance liquid chromatography (HPLC) and a radioisotope dilution assay (RIDA) to estimate the distribution of corrinoids—the cobalamins hydroxocobalamin (OH‐cbl), methylcobalamin (me‐cbl) and 5 ...
