Pathwayi: protoporphyrin-IX biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes coproporphyrinogen-III from 5-aminolevulinate.
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. Delta-aminolevulinic acid dehydratase (hemB)
  2. Porphobilinogen deaminase (hemC)
  3. no protein annotated in this organism
  4. Uroporphyrinogen decarboxylase (hemE)
This subpathway is part of the pathway protoporphyrin-IX biosynthesis, which is itself part of Porphyrin-containing compound metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes coproporphyrinogen-III from 5-aminolevulinate, the pathway protoporphyrin-IX biosynthesis and in Porphyrin-containing compound metabolism.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
