Type: | Domain | Name: | PGF-CTERM archaeal protein-sorting signal |
Description: | This entry represents a strictly archaeal putative protein-sorting motif, PGF-CTERM. It is the (predicted) recognition sequence for an exosortase homologue, archaeosortase. In some archaea, up to fifty proteins have this domain as their C-terminal region, usually preceded by a Thr-rich region likely to be heavily glycosylated. The removal of this sorting signal may be associated with a C-terminal prenyl group modification in the halobacterial major cell surface glycoprotein, an S-layer protein []. | Short Name: | PGF_CTERM |
