LITERATURE

hanging-drop vapour-diffusion method. 1.1A resolution crystal structure of MTHase, structures of MTHase in complex with maltose and trehalose are obtained at 1.2 A and 1.5 A resolution

Deinococcus radiodurans

hanging drop vapor diffusion method at 4°C. The crystal structure of the E283Q mutant enzyme in complex with the substrate, maltotriosyltrehalose is determined to 2.6 A resolution. The structure with maltotriosyltrehalose indicates that the enzyme has at least five substrate binding subsites and that Glu283 is the catalytic acid, and Asp252 is the nucleophile that attacks the C1 carbon in the glycosidic linkage of maltotriosyltrehalose
