Characterization of Escherichia coli OtsA, a trehalose-6-phosphate synthase from glycosyltransferase family 20

The trehalose-6-phosphase synthase, OtsA, a UDP-sugar dependent glycosyltransferase from Escherichia coli, has been cloned, overexpressed and crystallized in two forms suitable for X-ray diffraction studies.

The structure of S100A12 in a hexameric form and its proposed role in receptor signalling

The structure of a hexameric form of S100A12, a member of the S100 family of proteins, has been solved at 2.7 Å resolution. The results suggest a functional significance for the hexamer.
