Figure 6.

The OG1RF competence operon and its similarity with the competence operon of S. mutans. The ORFs essential for natural competence in S. mutans are shown in green as well as their homologues in OG1RF and V583. The ORF corresponding to the homologue of ComYD was not described in V583 [4], due to the presence of a probable prophage (EF1986-EF2043). The premature stop codon in EF1984 in V583 is indicated with an asterisk. ackA/EF1983 is represented in orange. The proteins encoded by the ORFs represented in white do not share any features of the known competence proteins or homology between S. mutans and E. faecalis; in S. mutans, ackA and ytxK are co-transcribed with the comY genes [47].
