Secret identities aren't  just for superheros anymore. Researchers have found that protein present in everything from amoebas to people is living the double life. Once it binds¹ the DNA², the protein called RFAH,  rips apart, and then refolds into different shape to do a different job. RFAH is transcriptional protein, attached to free from stretch of DNA. It determines if the genes³ is express or not. Once the protein has carried out its task, its helical structure unravels⁴. Within seconds, it refolds into parallel structure ,which has new role. This time, in translation will help the some produce amoe essence(acids) for new proteins. The study is in the journal : Cell. 

The next step is to find out if the amoe can refold into helix, after that, researchers want to see if protein similar to RFAH, which are present in all life on the earth. A capable and comparable molecular can torch(contortion) which mean a lot more bang for protein buck
