A, a stereo view of the superposition of FomA·DPO
(magenta) and the FomA·MgAMPPNP·fosfomycin
(blue) structures. The polypeptide chains are shown as ribbon
representations, AMPPNP, DPO, and fosfomycin molecules are shown in stick
representation. B, a superposition of the bound substrates in the
FomA·DPO (magenta), FomA·MgAMPPNP·fosfomycin
(blue), and NAGK·MgAMPPNP·NAG (orange)
complexes. Mg2+ cations are shown as crosses.
