Amylosucrase Mutant E328Q in a ternary complex with sucrose and maltoheptaose

The structure was published by Skov, L.K., Mirza, O., Sprogoe, D., et al., Albenne, C., Monsan, P., and Gajhede, M., in 2006 in a paper entitled "Crystal structure of the Glu328Gln mutant of Neisseria polysaccharea amylosucrase in complex with sucrose and maltoheptaose" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.16 Å and deposited in 2005.

The experimental data on which the structure is based was also deposited.

The PDB entry contains the structure of amylosucrase.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule is most likely monomeric.
