Protein Structure
UniProt Annotation
Function Catalyzes an early step in the biosynthesis of tetrapyrroles. Binds two molecules of 5-aminolevulinate per subunit, each at a distinct site, and catalyzes their condensation to form porphobilinogen. {ECO:0000269PubMed:11032836, ECO:0000269PubMed:19812033}.
Subcellular Localization
Disease Associations Acute hepatic porphyria (AHEPP) [MIM:612740]: A form of porphyria. Porphyrias are inherited defects in the biosynthesis of heme, resulting in the accumulation and increased excretion of porphyrins or porphyrin precursors. They are classified as erythropoietic or hepatic, depending on whether the enzyme deficiency occurs in red blood cells or in the liver. AHP is characterized by attacks of gastrointestinal disturbances, abdominal colic, paralyses and peripheral neuropathy. Most attacks are precipitated by drugs, alcohol, caloric deprivation, infections, or endocrine factors. {ECO:0000269PubMed:10706561, ECO:0000269PubMed:1309003, ECO:0000269PubMed:1569184, ECO:0000269PubMed:2063868}. Note=The disease is caused by mutations affecting the gene represented in this entry.
