B12: Structure and Reactivity The red, cyanide-containing cobalt-complex vitamin B12 (cyanocobalamin, CNCbl) is a relatively inert and physiologically rather inactive Co(III)-corrin. The bio- logically relevant B12-derivatives are the light sensitive and chemically more labile organometallic coenzyme ...
The ATP-binding cassette (ABC) transporter BtuCD mediates the uptake of vitamin B12 across the inner membrane of Escherichia coli. Previous structures have shown the conformations of apo states, but the transport mechanism has remained unclear. Here we r
