Over-production of porphyrins and heme in heterotrophic bacteria
Abstract:
In Escherichia coli, Pseudomonas aeruginosa, and Achromobacter metalcaligenes gamma-aminolevulinic acid synthase and gamma-aminolevulinic acid dehydratase appear to be the rate limiting enzymes of porphyrin and heme biosynthesis. Bypassing of these enzymes by addition of gamma-aminolevulinic acid or porphobilinogen results in overproduction of tetrapyrroles.
