?
ATP + H2O hydrolyzes both ATP and dATP at similar levels. The enzyme shows 5' to 3' and 3' to 5' DNA helicase activities and binds efficiently to partially duplex DNA containing a hairpin structure adjacent to a 6-nucleotide 5' or 3' single-stranded tail and one unpaired (flap) nucleotide in the complementary strand Streptococcus pneumoniae ADP + phosphate

additional information the enzyme is inefficient in in vitro replication of pT181, and perhaps as a consequence, this plasmid can not be established in Streptococcus pneumoniae Streptococcus pneumoniae ?
