2C4L

Structure of Neuraminidase Subtype N9 Complexed with 30 MM Sialic Acid (NANA, NEU5AC), Crystal Soaked for 24 Hours at 291 K and Finally Backsoaked for 30 Min in a Cryoprotectant Solution which did not contain NEU5AC


Changes made to a PDB entry after its initial release are considered to be either “major” or “minor”. The latest minor version of each major version is available as a file download. More information about the PDB versioning is available.
