| Short Name | ALAD_AS |
| description | Delta-aminolevulinic acid dehydratase () (ALAD) or porphobilinogen synthase []catalyses the second step in the biosynthesis of heme, the condensation of two molecules of5-aminolevulinate to form porphobilinogen. The enzyme is an oligomer composedof eight identical subunits. Each of the subunits binds an atom of zinc or ofmagnesium (in plants). A lysine has been implicated in the catalytic mechanism[]. The sequence of the region in the vicinity of the active site residue is conserved in ALAD from various prokaryotic and eukaryotic species. |
