Schematic representation of proposed cellulose polymerization and secretion complex in <i>G</i>. <i>hansenii</i>.

<p>With the activation of c-di-GMP, cytoplasmic membrane embedded AcsAB complexes transfer glucose into synthesized glucan chain. The elongated glucan chains in close proximity are bundled and pass through the pathway made by AcsD and finally extruded out of cell through the AcsC channel on the outer membrane.
