This entry represents a novel form of signal peptide that occurs as an N-terminal domain with a recognizable motif, reminiscent of the YSIRK signal peptide. (from Pfam)

The MucBP (MUCin-Binding Protein) domain is found in a wide variety of bacterial proteins, in several repeats. The domain is found in bacterial peptidoglycan bound proteins and is often found in conjunction with Pfam:PF00746 and Pfam:PF00560. (from Pfam)

This model describes a novel form of signal peptide that occurs as an N-terminal domain with a recognizable motif, reminiscent of the YSIRK and PEP-CTERM forms of signal peptide. This domain tends to occur on long, low-complexity (usually Serine-rich and heavily glycosylated) proteins of the Firmicutes, and (as with YSIRK) the majority of these proteins have the LPXTG cell wall-anchoring motif at the C-terminus.

This model describes the LPXTG motif-containing region found at the C-terminus of many surface proteins of Streptococcus and Streptomyces species. Cleavage between the Thr and Gly by sortase or a related enzyme leads to covalent anchoring at the new C-terminal Thr to the cell wall. Hits that do not lie at the C-terminus or are not found in Gram-positive bacteria are probably false-positive. A common feature of this proteins containing this domain appears to be a high proportion of charged and zwitterionic residues immediatedly upstream of the LPXTG motif. This model differs from other descriptions of the LPXTG region by including a portion of that upstream charged region.
