Functioni

Catalyzes an early step in the biosynthesis of tetrapyrroles. Binds two molecules of 5-aminolevulinate per subunit, each at a distinct site, and catalyzes their condensation to form porphobilinogen (By similarity).By similarity

Catalytic activityi

2 5-aminolevulinate = porphobilinogen + 2 H2O.

Cofactori

Zn2+By similarityNote: Binds 1 zinc ion per monomer.By similarity

Pathway: protoporphyrin-IX biosynthesis

This protein is involved in step 1 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. Probable porphobilinogen deaminase (hemC)
  3. Putative uroporphyrinogen-III synthase (AF_0116)
  4. no protein annotated in this organism
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 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.
