NamePorphobilinogen
SpeciesSaccharomyces cerevisiae
StrainBaker's yeast
DescriptionPorphobilinogen is an intermediate in tetrapyrrole biosynthesis pathway. Uroporphyrinogen-III, the final product in this pathway, is a major branch point that leads to biosynthesis of different tetrapyrrole compounds (e.g. porphyrins). Tetrapyrroles usually function as a metal-binding cofactor in many important enzymes, proteins and pigments, such as heme, chlorophyll, cobalamine, siroheme, and cofator F430. [Biocyc PWY-5189]
