Product Overview

Description	Recombinant Human Pterin-4-alpha-Carbinolamine Dehydratase is produced by our E.coli expression system and the target gene encoding Ala2-Thr104 is expressed with a 6His tag at the N-terminus.
Accession	P61457
Synonym	Pterin-4-Alpha-Carbinolamine Dehydratase; PHS; 4-Alpha-Hydroxy-Tetrahydropterin Dehydratase; Dimerization Cofactor of Hepatocyte Nuclear Factor 1-Alpha; DCoH; Dimerization Cofactor of HNF1; Phenylalanine Hydroxylase-Stimulating Protein; Pterin Carbinolamine Dehydratase; PCD; PCBD1; DCOH; PCBD
Gene Background	Pterin-4-α-Carbinolamine Dehydratase (PCBD1) is the founding member of the Pterin-4-α-Carbinolamine Dehydratase Family. PCBD1 is involved in Tetrahydrobiopterin biosynthesis. It seems to prevent the formation of 7-Pterins and accelerate the formation of Quinonoid-BH2. Furthermore, PCBD1 regulates the homodimerization of the transcription factor Hepatocyte Nuclear Factor 1 (HNF1) and enhances its transcriptional activity. Defects in PCBD1 are the cause of BH4-Deficient Hyperphenylalaninemia Type D (HPABH4D). HPABH4D is characterized by the excretion of 7-substituted Pterins in the urine of affected patients.

Target Details

Target Function	Involved in tetrahydrobiopterin biosynthesis. Seems to both prevent the formation of 7-pterins and accelerate the formation of quinonoid-BH2. Coactivator for HNF1A-dependent transcription. Regulates the dimerization of homeodomain protein HNF1A and enhances its transcriptional activity. Also acts as a coactivator for HNF1B-dependent transcription.
Subcellular Location	Cytoplasm. Nucleus.
Protein Families	Pterin-4-alpha-carbinolamine dehydratase family

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
