Fig 4
The most conserved and structurally aligned positions between CHITs and ELYSs (reported in Table 1).
The solvent accessible surface of these positions is plotted onto the reference models of CHIT (A) and ELYS (B) subfamilies (PDB accessions 4j0l of “loopful” plant chitinase from rye seed Secale cereale, and 4ok7 of bacteriophage SPN1S endolysin from Salmonella typhimurium, respectively), represented in cartoon style. In (C) and (D), the same models are rotated by 90° around the vertical axis.
