However, the chemical transformations that produce the biologically active form of vitamin D and how this active form of vitamin D affects the bones were described only recently.
In order to supply a safe and biologically active form of therapeutic protein, a selective removal of process-related impurities are required.
The enzyme crystallized as octamers with the monomers showing a classical TIM barrel fold which upon dimerization yields the biologically active form of the protein.
Dr. Bennett is also the CEO and Founder of PURIGENEX, a skin care company dedicated to natural, non-invasive products, utilizing a proprietary, biologically active form of topical collagen.
Studies suggest that the biologically active form of chromium (III) is an oligopeptide called Low-molecular-weight chromium-binding substance (LMWCr), which might play a role in the insulin signaling pathway.
The inhibition of PFK by ATP is unusual, since ATP is also a substrate in the reaction catalyzed by PFK; the biologically active form of the enzyme is a tetramer that exists in two possible conformations, only one of which binds the second substrate fructose-6-phosphate (F6P).
First, they did not confirm that the parasitoid was exposed to a biologically active form of the toxin.
For this, we used primers designed to amplify specifically the mature, biologically active form of these miRNAs (Fig. 1C).
The biologically active form of HIV-1 RT is a heterodimer consisting of two subunits, p66 (66 kDa) and p51 (51 kDa).
Collectively these results indicated that de novo repression of ICP0 mRNA accumulation was dependent upon the synthesis of a biologically active form of HSV's major transcriptional regulator, ICP4.
Our results indicated that the parasitoid was exposed to a biologically active form of the Cy1C protein while in the host but was not harmed by such exposure.
