... 14 of 28 gp5lysozymedomain,T4LandHEWLhaveacommon evolutionary origin. By comparing the crystal structure of T4L with bound substrate [36] to gp5, the inhibition of gp5 lysozyme activity in the ... moieties. In the gp5 trimer, the linker connecting the lysozyme domain to the b-helix prevents binding of the peptide portion of the substrate to the lysozyme domain. A...
