1jg9 is a 1 chain structure with sequence from Neisseria polysaccharea. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
AMYS_NEIPO Catalyzes the synthesis of alpha-glucan from sucrose. Catalyzes, in addition, sucrose hydrolysis, maltose and maltotriose synthesis by successive transfers of the glucosyl moiety of sucrose onto the released glucose, and finally turanose and trehalulose synthesis, these two sucrose isomers being obtained by glucosyl transfer onto fructose.[1]
