Plasmid segregation protein ParM

spinqualitylabelsall models plasmid segregation protein ParM complex with AMPPNP and Mg+2 ion (green) (PDB code 4a61) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D Function Plasmid segregation protein (ParM) is required for plasmid partition and accurate segregation of low-copy-number plasmid R1. Structural highlights ParM polymerizes into double helical protofilaments with repeats similar to F-actin. AMPPNP binding site. Mg coordination site. Water molecules are shown as red spheres.
