In PNAS this week, European scientists studied how cytoskeleton proteins affect viral DNA replication in bacteria. Using fusion proteins and fluorescence microscopy, they were able to show that the actin-like MreB cytoskeleton protein of E. coli and Bacillus subtilis is required for efficient viral DNA replication. It works by localizing the B. subtilis phage DNA and replication machinery to the cell membrane.
