Annotation score:4 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Involved in a type II secretion system (T2SS, formerly general secretion pathway, GSP) for the export of folded proteins across the outer membrane. This subunit would form the outer membrane channel.By similarity

Miscellaneous

Part of a cryptic operon that encodes proteins involved in type II secretion machinery in other organisms, but is not expressed in strain K12.

<p>This subsection of the ‘Family and domains’ section provides general information on the biological role of a domain. The term ‘domain’ is intended here in its wide acceptation, it may be a structural domain, a transmembrane region or a functional domain. Several domains are described in this subsection.<p><a href='/help/domain_cc' target='_top'>More...</a></p>Domaini

The N0, N1, N2 and N3 domains are periplasmic, while the secretin and S domains form a channel that is partially inserted in the outer membrane. The N1, N2 and N3 domains each form a periplasmic ring; the N0 domain was present but not resolved by electron microscopy. The secretin domain forms a double beta-barrel structure; the outer barrel has a diameter of about 110 Angstroms while the inner barrel forms the central gate with a small pore in the closed state.1 Publication
