Chains	Enzyme Name	Description	Catalytic Residues
A	porphobilinogen synthase M-CSA #230	5-Aminolaevulinic acid dehydratase (porphobilinogen synthase; EC 4.2.1.24) catalyses the dimerisation of two molecules of 5-aminolaevulinic acid to give porphobilinogen in a Knorr-type pyrrole synthesis. Porphobilinogen is the pyrrole precursor utilised by all living systems for the biosynthesis of tetrapyrroles, including haems, chlorophylls and corrins.
