Angewandte Chemie International Edition, Volume 63, Issue 31, July 29, 2024.The bifunctional CO‐dehydrogenase (CODH)/acetyl‐CoA synthase (ACS) complex couples catalysis at two sites connected by a tunnel transporting the generated CO. Hydrophobic sites with affinity for CO within the tunnel act in a bucket‐brigade fashion rather than as a simple tube.

Über die a-b-Isomerie der Cyano-aquo-corrinoide
Zeitschrift für Naturforschung B, 1967 Two isomers, a and b, of the tetracarbonic acid and some tri-, di- and monocarbonic acids, all derived from cobyric acid, have been crystallized. Two cobinamide monocarbonic acids have also been crystallized. The two crystalline tetracarbonic acids are both stable at 20 °C. They differ from each other in crystal shape.
