Function
function
Tetrapolymerization of the monopyrrole PBG into the hydroxymethylbilane pre-uroporphyrinogen in several discrete steps.
Miscellaneous
The porphobilinogen subunits are added to the dipyrromethane group.
Catalytic activity
- 4 porphobilinogen + H2O = hydroxymethylbilane + 4 NH4+
Cofactor
Note: Binds 1 dipyrromethane group covalently.
Pathway
Porphyrin-containing compound metabolism; protoporphyrin-IX biosynthesis; coproporphyrinogen-III from 5-aminolevulinate: step 2/4.
