Sucrose phosphorylase from Alteromonas mediterranea (7ZNP)

Sucrose phosphorylase are essential enzymes regulating the sucrose metabolism, and it has been shown that a loop rearrangement is essential to their catalytic cycle. Crystal structures from only five sucrose phosphorylase enzymes are available, and they all originate from organisms belonging to the Terrabacteria group. Here we present the crystal structure at 2.15 Å resolution of an enzyme from a Proteobacteria, Alteromonas mediterranea.
