FIGURE 7.

The Tat complex components and a model of TatC-signal peptide complex. (A) The single span TatA (PDB: 2MN7) and TatB (PDB: 2MI2) proteins were determined by NMR (Rodriguez et al., 2013; Zhang et al., 2014). The structure of 6 membrane spanning TatC [adapted from Rollauer et al. (2012) PDB: 4B4A] was solved by X-ray crystallography (Rollauer et al., 2012; Ramasamy et al., 2013). (B) The model of TatC binding with the Tat signal peptide in the groove adapted from Ramasamy et al. (2013). Only signal peptide and early mature region of the preprotein are indicated.
