A model for MioC and GidA-mediated linkage between replication initiation and cell division. (A) Schematic of mioC (blue) and gidA (red) transcription during the cell cycle from synchronized cell experiments (Theisen et al., 1993; Ogawa and Okazaki, 1994), and predicted expression of ymgF (dashed curve). Times of replication initiation and origin de-sequestration are indicated by arrows, with cell cycle pre-initiation (B period), replication (C period), and cell division (D period) shown above time line. (B) Cyclic inverse expression of mioC and gidA occur as a consequence of replication-dependent remodeling and subsequent remethylation (de-sequestration). See Discussion for detailed description.
