Protein

Delta-aminolevulinic acid dehydratase

Gene
hemB, MJ0643
Organism
Methanocaldococcus jannaschii (strain ATCC 43067 / DSM 2661 / JAL-1 / JCM 10045 / NBRC 100440) (Methanococcus jannaschii)
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.

Catalytic activityi

2 5-aminolevulinate = porphobilinogen + 2 H2O.

Cofactori

Binds 1 zinc ion per monomer By similarity.
