#Megaphages harbor mini-Cas proteins ideal for gene editing
“#Megaphages harbor mini-Cas proteins ideal for gene editing” A megaphage (left), a member of a bacteriophage family Biggiephage, injects its DNA — including genes for CasΦ (red) — into bacterial cells to turn the bacteria against the phage’s competitor (top). The reddish Pac-Man-like figures are CasΦ proteins, enzymes that cut up viral DNA. The genome…
