The residues forming the hydrophobic pocket and the hydrophobic lid anchor residue in the pilus-specific sortases.

The PDB codes for different structures are also given.The lid anchor residues are given in bold.*Identity of this residue is different from the corresponding residue in GBSSrtC1.**This position is occupied by Glu193 and its side chain is spatially conserved with Tyr171 side chain.Residues in parentheses indicate that the residue does not occupy the same spatial position as the structurally corresponding residue in GBSSrtC1.§While the Cα's of HB-lid residues do not coincide with Leu47 upon superposition, the orientation and spatial position of the sidechains over the hydrophobic pocket is conserved.
