Crystal structure of sulfolobus tokodaii hypothetical maltooligosyl trehalose synthase

The structure was published by Cielo, C.B.C., Okazaki, S., Suzuki, A., et al., Masui, R., Kuramitsu, S., and Yamane, T., in 2010 in a paper entitled "Structure of ST0929, a putative glycosyl transferase from Sulfolobus tokodaii" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2009.

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

The PDB entry contains the structure of 704aa long hypothetical glycosyltransferase. This molecule has the UniProt identifier Q973H2 (Q973H2_SULTO)search. The sample contained 704 residues which is 100% of the natural sequence. Out of 704 residues 704 were observed and are deposited in the PDB.

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.
