| Type: | Domain | Name: | Type II secretion system protein G |
| Description: | The general secretion pathway, or type II pullulanase-like machinery, is responsible for the transport of proteins from the periplasm across the outer membrane in Gram-negative bacteria [, ]. This entry includes protein G (e.g. , ) involved in this pathway. The PulG protein () is thought to be anchored in the inner membrane with its C terminus directed towards the periplasm []. Together with other members of the secretion machinery, it is thought to assemble into a pilus-like structure that may function as a dynamic mechanism to push secreted proteins out of the cell. The polypeptide is organised into a long N-terminal alpha-helix followed by a loop region that separates it from a C-terminal anti-parallel beta-sheet []. | Short Name: | T2SS_protein-G |
