CRYSTAL STRUCTURE OF AMYLOMALTASE FROM THERMUS AQUATICUS, A GLYCOSYLTRANSFERASE CATALYSING THE PRODUCTION OF LARGE CYCLIC GLUCANS

The structure was published by Przylas, I., Tomoo, K., Terada, Y., et al., Fujii, K., Saenger, W., and Strater, N., in 2000 in a paper entitled "Crystal structure of amylomaltase from thermus aquaticus, a glycosyltransferase catalysing the production of large cyclic glucans." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 1999.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of AMYLOMALTASE. This molecule has the UniProt identifier O87172 (MALQ_THETH)search. The sample contained 500 residues which is 100% of the natural sequence. Out of 500 residues 500 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
