Scientists develop new color-coded test for protein folding

...oated with cytochrome c began clumping together--a process that caused the solution to quickly change from red to blue as the acidity increased. The researchers were surprised to discover that, when the pH was raised from 4 to 10, the blue solution turned reddish once again--a strong indication that some cy...

Probing The Promise And Perils Of Nanoparticles

...nd similar nanoparticles get into cells involves a process called polycation-mediated endocytosis. But Hong's experiments suggest that nanoscale hole formation may be at least as important in allowing materials to travel through membranes. The work that Banaszak Holl, Hong and Leroueil will discuss is one o...

DNA Recombination and Repair—A New Twist to RecA Function

...e the repair of DNA lesions during replication—the process by which a DNA molecule is copied to make two. RecA is also an ATPase, an enzyme capable of hydrolyzing (breaking down) ATP, when bound to DNA. RecA uses ATP to carry out strand exchange over long sequences and impose direction to the exchange, to b...
