Protein

Delta-aminolevulinic acid dehydratase

Gene

hemB

Organism
Clostridium josui
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

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
