The hydrophobic residues in the active sites of GBSSrtC1 and the housekeeping sortases.

Residues in parentheses indicate that the residue does not occupy the same spatial position as the structurally corresponding residue in GBSSrtC1.§Sidechain conformations are conserved but not the Cα position.括号内的残基表示，该残基与GBSSrtC1中的结构对应残基不处于相同空间位置。§侧链构象保守，但Cα原子位置并不保守。
