type II secretion system protein I; This model represents GspI, one of two proteins highly conserved at their N-termini and described by pfam02501 but easily separable phylogenetically. The other is GspJ. Both GspI and GspJ are proteins of the type II secretion pathway, or main terminal branch of the general secretion pathway. This pathway carries proteins across the outer membrane. Note that proteins of type II secretion are cryptic in E. coli K-12 - present but not yet demonstrated to act on any target.

Type II secretion system (T2SS), protein I; The Type II secretion system, also called Secretion-dependent pathway (SDP), is responsible for the transport of proteins across the outer membrane first exported to the periplasm by the Sec or Tat translocon in Gram-negative (diderm) bacteria. As members of the T2SJ family, members of the T2SI family are pseudopilins containing prepilin signal sequences.

 8-31 3.72e-04

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).
