Cofactor	Binds 1 zinc ion per monomer. Ref.9
Enzyme regulation	Inhibited by divalent lead ions. Ref.8
Pathway	Porphyrin metabolism; protoporphyrin-IX biosynthesis; coproporphyrinogen-III from 5-aminolevulinate: step 1/4.
Subunit structure	Homooctamer. Ref.8 Ref.12
Miscellaneous	Present with 11600 molecules/cell in log phase SD medium. Ref.6
Sequence similarities	Belongs to the ALADH family.
