In the next, light-initiated (photochemical) reaction, only the desired thioether bonds are formed—no side reactions occur at other locations in the peptide chain. “Synthetic glycopeptide antigens containing structural elements typic...

The more we know about plants, the more complex their interactions seem to be, so it may be as hard to predict the outcome as when...

Penn researchers link cell's protein recycling systems

They also showed that by simply expressing extra HDAC6, neurodegeneration was prevented in flies with proteasome impairment. Taylor’s group then moved on to fly models of human neurodeg...
