Structure of molecular light switch -- channelrhodopsin -- determined - Science Daily


Science Daily
The chain of water molecules then breaks, causing the three gates to open and producing a pore extending right through the protein. "Our results are a milestone in optogenetics," says Gordeliy, "as they open up the possibility of constructing new ...

Searching for the CRISPR Swiss-army Knife - Technology Networks


Technology Networks
Recently, this team obtained the molecular structure of the CRISPR-Cpf1 complex after target cleavage. This protein from the Cas family has the ability to specifically unwind and cleave the DNA to initiate the modification process. This property “will ...
