Protein

Delta-aminolevulinic acid dehydratase

Gene

hemB

Organism
Bradyrhizobium diazoefficiens (strain JCM 10833 / IAM 13628 / NBRC 14792 / USDA 110)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

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. Required for nodule development.1 Publication

Catalytic activityi

2 5-aminolevulinate = porphobilinogen + 2 H2O.1 Publication

Cofactori

Magnesium.1 Publication
