spinqualitylabelsall models Se-Met MglA (grey) complex with MglB (green, pink), GTP-γS, Mg+2 ion (green) and sulfate (PDB code 6izw). Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image Function Gliding protein or Mutual gliding-motility protein or Gliding motility protein (MglA and MglB). MglA is related to GTPase and is required for the normal operation of adventurous and social motility and multicellular development of some bacteria[1]. InMyxococcus xanthus MglA regulates the movement of the bacteria on surfaces. MglB is MglA cognate GTPase activating protein[2]. Structural highlights The 3D structure of the complex of MglA monomer and MglB dimer shows their hydrophilic and hydrophobic interacting surfaces[3]. The bound GTP-γS is hydrogen bonded to an Arg residue in MglA.
