Delta-aminolevulinic acid dehydratase, chloroplastic
Gene
HEMB, ALAD
Organism
Glycine max (Soybean) (Glycine hispida)
Status

Functioni

Is committed to plant tetrapyrrole synthesis.
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 2 magnesium ions per monomer. The first magnesium ion is required for catalysis. The second functions as allosteric activator By similarity.
