LITERATURE
in complex with myo-inositol
-
X-ray crystal structure
-
mutant Y247S/Y251S in the absence and presence of myo-inositol as well as mutant Y246S/Y247S/Y248S/Y251S, both mutant proteins crystallize as monomers, are very similar to one another, and have no change in the active site region
wild-type and D274N mutant PI-PLC
-
recombinant PI-PLC
-
purified recombinant wild-type enzyme and mutant Y253S complexed with 1,2-dibutyroyl-sn-glycero-3-phosphocholine, hanging drop vapour diffusion method, mixing of 0.0015 ml of 10 mg/ml protein, 50 mM myo-inositol and 2.5 mM 1,2-dibutyroyl-sn-glycero-3-phosphocholine, with 0.0015 ml of reservoir solution containing 150 mM ammonium acetate, 100 mM sodium acetate, pH 4.6, with 1 mM Mg(NO3)2 (100 mM for the mutant enzymes), and 16-20% PEG 4000, 20°C, 2 weeks, X-ray diffraction structure determination and analysis at 2.16-2.3 A resolution
