Frequently Asked Questions
Still have questions?
Native proteins are proteins in their natural form, extracted from their natural source.
A recombinant protein is a modified version of a native protein produced to increase protein production or modify gene sequences.
Competitive Inhibition: Competitive enzyme inhibitors compete with substrates for the enzyme's active site. Because fewer substrate molecules can bind to the enzyme, the reaction rate is decreased.
Non-Competitive Inhibition: Non-competitive enzyme inhibitors bind to sites other than the enzyme's active site. This is called an allosteric site.
Uncompetitive Inhibition: Uncompetitive inhibitors cannot bind to free enzymes. Instead, it binds to enzyme-substrate complexes to form an inactive enzyme-substrate complex. This type of inhibition is rare.
A growth factor is a naturally occurring group of proteins that stimulate cell proliferation and the growth of specific tissues. The term “growth factor” includes peptides that stimulate or inhibit the progression of cells through mitosis.
