Abstract:
2,3-Diketo-5-methylthiopentyl-1-phosphate enolase (DK-MTP-1P enolase) from Bacillus subtilis was crystallized using the hanging-drop vapour-diffusion method. Crystals grew using PEG 3350 as the precipitant at 293 K. The crystals diffracted to 2.3 A resolution at 100 K using synchrotron radiation and were found to belong to the monoclinic space group P2(1), with unit-cell parameters a = 79.3, b = 91.5, c = 107.0 A, beta = 90.8 degrees. The asymmetric unit contained four molecules of DK-MTP-1P enolase, with a V(M) value of 2.2 A(3) Da(-1) and a solvent content of 43%.
