DprA/Smf protein localizes at the DNA uptake machinery in competent Bacillus subtilis cells

摘要

BackgroundDprA is a widely conserved bacterial protein and has been shown to confer an important function during transformation in competent cells, possibly through protection of incoming DNA. B. subtilis DprA (called Smf) and has been shown to play an important role during transformation with chromosomal DNA, but its mode of action is unknown.
