LITERATURE
purified wild-type enzyme enzyme PntM substrate-free, and PntM with bound substrate pentalenolactone F, product pentalenolactone, and substrate analogue 6,7-dihydropentalenolactone, and recombinant PntM F232L, M77S, M81A, M81C, and M81C-BME mutants with bound pentalenolactone F, sitting drop vapor diffusion method, mixing of 0.001 ml of 16.8 mg/mL protein in 10 mM Tris-HCl, 15 mM NaCl, and 10% glycerol, with 0.001 ml of reservoir solution containing 1.2 M sodium citrate, 10% glycerol, and 100 mM bicine, pH 9.0, 15°C, followed by cross-microseeding technique, X-ray diffraction structure determination and analysis at 1.54 A and 2.06-2.12 A resolution, respectively, molecular replacement using the crystal structure of polyene macrolide epoxidase PimD, PDB ID 2X9P, as search model
