Gene Functions References

we used bioinformatics and computational biology tools to evaluate the role(s) of the C-terminal tail dynamics in the structure and conformational dynamics of the murine ALAS2 homodimer active site loop. PMID: 29958424
Data indicate that the 5-aminolevulinate synthase (mALAS2) active site loop harboring the simultaneous seven amino acid mutations was less flexible than the wild type loop. PMID: 27928941
We propose that the N-terminal truncation offers a cell-specific ALAS2 regulatory mechanism without hindering heme synthesis PMID: 26854603
N150F ALAS variant catalyzes the forward reaction at a mere 1.2-fold faster rate than that of the reverse reaction. PMID: 26511319
Light treatments revealed that ALAS2 expression results in an increase in cell death in comparison to aminolevulinic acid (ALA) treatment producing a similar amount of protoprophyrin IX. PMID: 24718052
The rate of ALA release is also controlled by a hysteretic kinetic mechanism (observed as a lag in the ALA external aldimine formation progress curve), consistent with conformational changes governing the dissociation of ALA from ALAS. PMID: 24920668
impaired mitochondrial [Fe-S] cluster biogenesis in Mfrn1(gt/gt) cells results in elevated IRP1 RNA-binding that attenuates ALAS2 mRNA translation and protoporphyrin accumulation PMID: 24509859
Data suggest the reaction of glycine with ALAS follows a three-step kinetic process, and the substrate 5-aminolevulinate induces a conformational change in ALAS which may modulate product release. PMID: 12191993
Aberrant iron accumulation and peroxidized state of (ALAS2)-deficient definitive erythroblasts PMID: 12393610
mechanism of up-regulation in erythroleukemia cells exposed to hypoxia PMID: 12393745
These findings thus suggest that heme may regulate a wide variety of hitherto unrecognized genes, and further analysis of these genes may clarify their role in erythroid cell differentiation. PMID: 16356476
Gene expression and enzymatic assays indicate that erythroid 5-aminolevulinic acid synthase (Alas2) is decreased in hem6 animals, suggesting a mechanism that could account for the anemia. PMID: 18780836

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.
