CC -!- FUNCTION: Catalyzes an early step in the biosynthesis of tetrapyrroles.
CC Binds two molecules of 5-aminolevulinate per subunit, each at a
CC distinct site, and catalyzes their condensation to form porphobilinogen
CC (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 5-aminolevulinate = H(+) + 2 H2O + porphobilinogen;
CC Xref=Rhea:RHEA:24064, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:58126, ChEBI:CHEBI:356416; EC=4.2.1.24;
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC Note=Binds 8 zinc ions per octamer. Requires four zinc ions per octamer
CC for full catalytic activity. Can bind up to 2 zinc ions per subunit.
CC {ECO:0000250};
CC -!- ACTIVITY REGULATION: Can alternate between a fully active homooctamer
CC and a low-activity homohexamer. A bound magnesium ion may promote the
CC assembly of the fully active homooctamer. The magnesium-binding site is
CC absent in the low-activity homohexamer. Inhibited by compounds that
CC favor the hexameric state. Inhibited by divalent lead ions. The lead
CC ions partially displace the zinc cofactor (By similarity).
CC {ECO:0000250}.
CC -!- PATHWAY: Porphyrin-containing compound metabolism; protoporphyrin-IX
CC biosynthesis; coproporphyrinogen-III from 5-aminolevulinate: step 1/4.
CC -!- SUBUNIT: Homooctamer; active form. Homohexamer; low activity form (By
CC similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the ALAD family. {ECO:0000305}.
