beta-N-acetylglucosaminidase. This family has previously been described as a hyaluronidase. However, more recently it has been shown that this family has beta-N-acetylglucosaminidase activity.

Glycosyl hydrolase family 20, domain 2. This domain has a zincin-like fold.

Gram-positive signal peptide, YSIRK family. Many surface proteins found in Streptococcus, Staphylococcus, and related lineages share apparently homologous signal sequences. A motif resembling [YF]SIRKxxxGxxS[VIA] appears at the start of the transmembrane domain. The GxxS motif appears perfectly conserved, suggesting a specific function and not just homology. There is a strong correlation between proteins carrying this region at the N-terminus and those carrying the Gram-positive anchor domain with the LPXTG sortase processing site at the C-terminus.

YSIRK type signal peptide. Many surface proteins found in Streptococcus, Staphylococcus, and related lineages share apparently homologous signal sequences. A motif resembling [YF]SIRKxxxGxxS[VIA] appears at the start of the transmembrane domain. The GxxS motif appears perfectly conserved, suggesting a specific function and not just homology. There is a strong correlation between proteins carrying this region at the N-terminus and those carrying the Gram-positive anchor domain with the LPXTG sortase processing site at the C-terminus.

PavB family adhesin N-terminal domain. This HMM describes the portion of PavB from Streptococcus pneumoniae, and closely related proteins from Streptococcus mitis and Streptococcus pseudopneumoniae, N-terminal to the repetitive region with variable numbers of SSURE (Streptococcal Surface REpeats) regions (see PF11966), which bind fibronectin. The PavB region is notable, in part, for its rare variant, WSIRR, of the YSIRK motif signal peptide. Full-length versions of proteins from this family have a C-terminal LPXTG-containing region for sortase-mediated anchoring to the cell wall.
