Fig. 8.

Schematic representation of the possible constituents of the putative cell elongation complex in E. coli. MraY, MurG and MreB interact with the MreCD. The complex of MreBCD, PBP2 and RodA was published by Kruse et al. (2005). As MreC was shown to interact with three of the four high-molecular-weight class A PBPs of B. subtilis (Van den Ent et al., 2006), it was postulated that PBP1A could be part of the complex (see Discussion). For simplicity only one MurG molecule is illustrated. However, the possibility of formation of dimmers that might be part of the complex is not excluded.
