WebbAll bacteria, both pathogenic and saprophytic, are unicellular organisms such reproduce by dual fission. Most bacteria are capable of separate metabolic existence and growth, but species of Chlamydia and Rickettsia are obligately intracellular organisms. Bacteria cells are extremely smallish and are majority conveniently measured in microns (10-6 m). Webb1 nov. 2012 · Translocation across the inner membrane to the periplasmic space in E. coli requires the Sec translocase or the twin arginine translocase (Tat) pathway. While substrates are translocated through the Sec channel in an unfolded state (Fig. 2 ) (for review, see Driessen & Nouwen, 2008 ), the Tat machinery can export proteins across the …
