MAPKSP1 Protein, Human (His)
Based on 1 Customer Validation
The MAPKSP1 protein, also known as porphobilinogen deaminase (HMBS), is crucial in the heme biosynthetic pathway and catalyzes the sequential polymerization of four porphobilinogen molecules to form hydroxymethyl bixane. The process begins with the assembly of the dipyrromethane cofactor of porphobilinogen or preuroporphyrinogen. MAPKSP1 Protein, Human (His) is the recombinant human-derived MAPKSP1 protein, expressed by E. coli , with N-6*His labeled tag.
- Species: Human
- Source: E. coli

Storage:Stored at -80°C for 1 year from date of receipt. It is stable at -20°C for 3 months after opening. It is recommended to freeze aliquots at -80°C for extended storage. Avoid repeated freeze-thaw cycles.
Biological Activity
The MAPKSP1 protein, also known as porphobilinogen deaminase (HMBS), is crucial in the heme biosynthetic pathway and catalyzes the sequential polymerization of four porphobilinogen molecules to form hydroxymethyl bixane.

HMBS, also known as Porphobilinogen deaminase, plays a crucial role in the heme biosynthetic pathway by catalyzing the sequential polymerization of four molecules of porphobilinogen, resulting in the formation of hydroxymethylbilane, also referred to as preuroporphyrinogen. The catalytic process commences with the assembly of the dipyrromethane cofactor, formed either from two molecules of porphobilinogen or from preuroporphyrinogen, by the apoenzyme. The covalently linked cofactor serves as a primer, orchestrating the assembly of the tetrapyrrole product around it. In the final step of catalysis, the product, preuroporphyrinogen, is released, while the cofactor remains bound to the holodeaminase intact, highlighting the intricate and essential role of HMBS in the synthesis of heme.
