From: Structure and tailspike glycosidase machinery of ORF212 from E. coli O157:H7 phage CBA120 (TSP3)
The location of the confirmed TSP3 and postulated TSP1 active sites. The molecular surface of the trimer is colored according to the vacuum electrostatic potential calculated with PyMol with red color depicting negatively charged regions and blue color depicting positively charged regions. The active sites are located in negatively charged pockets along grooves formed at the subunit interfaces.
