FIGURE 7.

Modeled surface presentation of Hyl. Models of the Hyl monomer (A) and dimer (B) as they may be presented on the surface of the bacterium. Only the structures from population A of the SAXS-generated modules are shown because the two populations are very similar in overall organization. The dashed arrows represent the path of processive cleavage of hyaluronan (HA) chains through the PL8 domain active sites. The dark, bending lines represent the unmodeled C-terminal portions of Hyl that tether the protein to the peptidoglycan through a sortase-mediated process.
