This protein is involved in step 6 of the subpathway that synthesizes cob(II)yrinate a,c-diamide from precorrin-2 (aerobic route).
Proteins known to be involved in the 10 steps of the subpathway in this organism are:
  1. Cobalamin biosynthesis protein CobIJ (cobIJ)
  2. no protein annotated in this organism
  3. Cobalamin biosynthesis protein CobIJ (cobIJ)
  4. Precorrin-4 C(11)-methyltransferase (cobM)
  5. no protein annotated in this organism
  6. Precorrin-6A reductase (cobK)
  7. Precorrin-6Y C(5,15)-methyltransferase [decarboxylating] (cobL)
  8. Precorrin-8X methylmutase (cobH)
  9. Hydrogenobyrinate a,c-diamide synthase (cobB), Hydrogenobyrinate a,c-diamide synthase (cobB)
  10. no protein annotated in this organism
This subpathway is part of the pathway adenosylcobalamin biosynthesis, which is itself part of Cofactor biosynthesis.
