This protein is involved in step 1 of the subpathway that synthesizes cob(II)yrinate a,c-diamide from sirohydrochlorin (anaerobic route).
Proteins known to be involved in the 10 steps of the subpathway in this organism are:
  1. Sirohydrochlorin cobaltochelatase (cbiK)
  2. Cobalt-precorrin-2 C(20)-methyltransferase (cbiL)
  3. Probable cobalt-factor III C(17)-methyltransferase (cbiH)
  4. Cobalt-precorrin-4 C(11)-methyltransferase (cbiF)
  5. Cobalt-precorrin-5A hydrolase (cbiG)
  6. Cobalt-precorrin-5B C(1)-methyltransferase (cbiD)
  7. Cobalt-precorrin-6A reductase (cbiJ)
  8. Cobalt-precorrin-6B C(15)-methyltransferase (decarboxylating) (cbiT), Cobalt-precorrin-7 C(5)-methyltransferase (cbiE)
  9. Cobalt-precorrin-8 methylmutase (cbiC)
  10. Cobyrinate a,c-diamide synthase (cbiA)
This subpathway is part of the pathway adenosylcobalamin biosynthesis, which is itself part of Cofactor biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes cob(II)yrinate a,c-diamide from sirohydrochlorin (anaerobic route), the pathway adenosylcobalamin biosynthesis and in Cofactor biosynthesis.
