|
|
|
|
|
|
||
| UniProt code: P05373. |
|
||
| Organism: | |
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast). |
| Taxonomy: | |
Eukaryota; Fungi; Dikarya; Ascomycota; Saccharomycotina; Saccharomycetes; Saccharomycetales; Saccharomycetaceae; Saccharomyces. |
|
||
|
||
| 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. |
|
