  1. aR6smR integrated an rpsL allele conferring resistance to streptomycin (smR). Each mutated and WT alleles presented in the table was co-transformed with this rpsL allele that was used as a surrogate marker for the selection of transformants (see Methods). Although not indicated, every transformants in Table 4 are smR
  2. bWT, S. pneumoniae R6 WT gene sequence; R, S. pneumoniae R6-DP1R gene sequence
  3. cEOP, efficiency of plaquing. Represents the ratio of phage titers from the test strain to the indicator strain R6 WT. Measured from three independent triplicate
