3.13.1.3	crystal structure of DszB and an inactive mutant of DszB in complex with substrate at resolution of 1.8 A or better	
3.13.1.3	DszB and DszB C27S mutant complexed with biphenyl-2-sulfinic acid are crystallized. The crystals of DszB belong to the orthorhombic P2(1)2(1)2(1) space group, with unit-cell parameters a = 36.7 A, b = 82.6 A, c = 139.6 A, and contain one molecule of DszB in the asymmetric unit. Crystals of DszB C27S complexed with biphenyl-2-sulfinic acid belong to space group C2 with unit-cell parameters a = 153.4 A, b = 45.9 A, c = 112.9 A, beta = 115.93°
