enzyme

Now, a team of international scientists, including University of Michigan researchers, have used advanced microscopy to image how ribosomes recruit to mRNA while it's being transcribed by an enzyme called RNA polymerase, or RNAP.

The team identified a family of enzymes called metalloproteases that became more active as more tissue was lost.

This chemically reactive form was then tailored to interact with an enzyme abundant in cancer cells, known as thioredoxin reductase.

It's based on the way cellular states including metabolism can be controlled by modulating the activities of enzymes.

By examining the fecal samples from people, they linked a specific enzyme in bacteria, beta-glucuronidase, as a key factor that allows the drug to enter the bloodstream.
