Biosynthesis of vitamin B12: identity of fragment extruded during ring contraction to the corrin macrocycle.
AUTOR(ES)
Battersby, A R
RESUMO
Incorporation experiments with labeled sirohydrochlorin and trimethylisobacteriochlorin demonstrate that ring contraction in vivo to the corrin macrocycle of vitamin B12 liberates acetic acid. The C-20 atom of the precursors becomes the acetate carboxyl carbon.
