LITERATURE
in complex with UDP-N-acetylglucosamine and fosfomycin, sitting drop vapor diffusion method, using 25% (w/v) PEG 3350, 0.1 M bis-Tris pH 6.5
at 19°C, from 10 mM MES, pH 6.4, 10% (w/v) polyethylene glycol 20000, in the presence of 5 mM UDP-N-acetyl-D-glucosamine and 5 mM phosphoenolpyruvate
crystallization of substrate-free enzyme, two-domain structure with an unusual fold, inside out alpha/beta barrel, which is built up from the 6fold repetititon of one folding unit, structure analysis
-
in complex with inhibitor T6361
in complex with substrates, hanging drop vapor diffusion method, using 0.1 M Bis-Tris (pH 5.5), 0.2 M NH4OAc, 25% (w/v) PEG 3350
mutant D305A, in presence of phosphoenolpyruvate and UDP-N-acetyl-D-glucosamine

X-ray structure analysis of ligated and unligated MurA
-
crystallization of the enzyme complexed with UDP-N-acetylglucosamine and fosfomycin, two-domain structure with the active site located between them, structure and substrate binding analysis
-
in complex with inhibitor cnicin and substrate UDP-N-acetylglucosamine, at 2.0 A resolution. The enzyme catalyzes the formation of a covalent adduct between cnicin and UDP-N-acetylglucosamine via an anti-Michael 1,3-addition of UDP-N-acetylglucosamine to an alpha,beta-unsaturated carbonyl function in cnicin thus forming a noncovalent suicide inhibitor
MurA is crystallized in the presence of sodium phosphite and UDP-N-acetylmuramic acid using the hanging drop vapor diffusion method, the MurA cocrystal structure with UDP-N-acetylmuramic acid and phosphite reveals a new staged MurA conformation in which the Arg397 side chain tracked phosphite out of the catalytic site
in complex with UDP-N-acetylglucosamine and fosfomycin, to 2.3 A resolution. The active-site loop can adopt one of the three major conformations: a fully open conformation, a half-open conformation, and a closed conformation. Fosfomycin can bind without inducing a large change in the half-open conformation of the binary complex with UDP-N-acetylglucosamine
in the apo-form, as well as in a complex with UDP-N-acetylglucosamine and fosfomycin using ammonium sulfate as the precipitant, hanging drop vapour diffusion method
