Description

The fumarate hydratase/FH protein plays a key role in cellular processes as it catalyzes the hydration of fumarate to L-malate in the tricarboxylic acid (TCA) cycle, which is essential for energy production through the production of NADH . Fumarate hydratase/FH Protein, Human is the recombinant human-derived Fumarate hydratase/FH protein, expressed by E. coli , with tag free.
Background

Fumarate Hydratase (FH) is an enzyme that catalyzes the reversible conversion of fumarate to L-malate. This stereospecific interconversion plays a pivotal role in the tricarboxylic acid (TCA) cycle, a central metabolic pathway involved in energy production. Specifically, FH facilitates the hydration of fumarate to L-malate, contributing to a key transition step in the TCA cycle. Experiments in various species suggest that specific isoforms of FH may act in defined pathways and exhibit preferences for one direction of the reaction over the other. By participating in the TCA cycle, FH ensures the efficient generation of energy in the form of NADH, highlighting its essential role in cellular metabolism.
Biological Activity

Measured by its ability to catalyze the conversion of fumarate to malic acid. Defines one unit of enzyme activity as 1 nmmol NADH per minute of protein produced as one unit of enzyme activity. The specific activity is 157.155 U/mg.

Help & FAQs
  • How should lyophilized recombinant proteins be reconstituted and stored?

    1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss. 2. Taking 10 μg as an example, first add 20 μL of reconstituted solution provided by MCE and use a pipette to gently resuspend the lyophilized protein until it is fully dissolved.. (For most proteins, the reconstitution solution we provide is sterile water. If a diluent other than water is required, it will be indicated in the product's Certificate of Analysis (COA).). 3. Add an additional 80 μL of buffer/culture medium containing carrier protein (either 0.1% BSA, 5% HSA, 10% FBS, or 5% trehalose), and then use a pipette to gently mix until uniform. The final concentration is should not be lower than 100 μg/mL. 4. Aliquot at least 20 μL per tube. 5. After aliquoting, store it frozen at a temperature ranging from -20ºC to -80ºC, and it can be preserved for 3 to 6 months.

  • How should solution-form recombinant proteins be stored?

    1. The product can be stored in its original form and diluted as needed upon use. 2. Alternatively, dilute with a buffer/culture medium containing a carrier protein (either 0.1% BSA, 5% HSA, 10% FBS, or 5% alginate), mix well by pipetting, and ensure that

  • Why is it necessary to add carrier proteins?

    Carrier proteins are commonly added to enhance the stability of recombinant proteins, preventing them from adhering to the walls of the container during freezing or thawing processes. Plastic tubes have a certain adsorptive capacity for proteins, which may lead to difficulty in separating the protein from the tube walls, resulting in a decrease in the actual concentration of the protein in the solution and thus affecting its activity. To minimize such losses, it is recommended to add a commonly used carrier protein solution prior to the long-term storage of recombinant protein products.

  • Carrier protein types and options?

    In cases where the carrier protein is not expected to influence the experimental outcomes, an appropriate carrier protein, such as 0.1% BSA (Bovine Serum Albumin), 5% HSA (Human Serum Albumin), 10% FBS (Fetal Bovine Serum), or 5% trehalose, can be incorpo
