Protein

Delta-aminolevulinic acid dehydratase

Gene

ALAD

Organism
Pongo abelii (Sumatran orangutan) (Pongo pygmaeus abelii)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript 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 (By similarity).By similarity

Catalytic activityi

2 5-aminolevulinate = porphobilinogen + 2 H2O.

Cofactori

Zn2+By similarityNote: Binds 8 zinc ions per octamer. Requires four zinc ions per octamer for full catalytic activity. Can bind up to 2 zinc ions per subunit.By similarity

Enzyme regulationi

Can alternate between a fully active homooctamer and a low-activity homohexamer. A bound magnesium ion may promote the assembly of the fully active homooctamer. The magnesium-binding site is absent in the low-activity homohexamer. Inhibited by compounds that favor the hexameric state. Inhibited by divalent lead ions. The lead ions partially displace the zinc cofactor (By similarity).By similarity
