prepilin-type N-terminal cleavage/methylation domain; This model describes many but not all examples of the N-terminal region of bacterial proteins that resemble type IV pilins at their N-terminus, with a cleavage site G^FxxxE followed by a hydrophobic stretch. The new N-terminal residue, usually Phe, is methylated. Separate domains of the prepilin peptidase appear responsible for cleavage and methylation. Proteins with this N-terminal region include type IV pilins and other components of pilus biogenesis, competence proteins, and type II secretion proteins. Typically several proteins in a single operon have this N-terminal domain. The N-terminal cleavage and methylation site is described by PROSITE motif PS00409 as [KRHEQSTAG]-G-[FYLIVM]-[ST]-[LT]-[LIVP]-E-[LIVMFWSTAG](14).

competence type IV pilus major pilin ComGC; ComGC, encoded in the comG operon, is the major pilin of a type IV pilus involved in natural transformation of monoderm bacteria (those lacking an outer membrane) such as Bacillus subtilis and Streptococcus pneumoniae. In the seed alignment, Bacillus proteins have a pair of Cys residues likely to form a disulfide bond while Streptococcus proteins lack Cys residues.

competence type IV pilus major pilin ComGC; ComGC, encoded in the comG operon, is the major pilin of a type IV pilus involved in natural transformation of monoderm bacteria (those lacking an outer membrane) such as Bacillus subtilis and Streptococcus pneumoniae. In the seed alignment, Bacillus proteins have a pair of Cys residues likely to form a disulfide bond while Streptococcus proteins lack Cys residues.

type II secretion system protein H; This model represents GspH, protein H of the main terminal branch of the general secretion pathway, also called type II secretion. It transports folded proteins across the bacterial outer membrane and is widely distributed in Gram-negative pathogens.

Pilin (bacterial filament); Proteins with only the short N-terminal methylation site are not separated from the noise. The Prosite pattern detects those better.

Verru_Chthon cassette protein D; This model describes a nearly twenty member protein family in Verrucomicrobium spinosum and a somewhat smaller paralogous family in Chthoniobacter flavus. All members share a type IV pilin-like N-terminal leader sequence (TIGR02532). These proteins occur in the four-gene Verru_Chthon cassette, in which two other genes likewise encode a cleavage/methylation domain. Most of these cassettes occur next to an unusually large PEP-CTERM protein with an autotransporter domain. [Cell envelope, Surface structures]
