1d3c Summary



The structure was published by Uitdehaag, J.C., Kalk, K.H., van Der Veen, B.A., Dijkhuizen, L., and Dijkstra, B.W., in 1999 in a paper entitled "The cyclization mechanism of cyclodextrin glycosyltransferase (CGTase) as revealed by a gamma-cyclodextrin-CGTase complex at 1.8-A resolution." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.78 Å and deposited in 1999.

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

The PDB entry contains the structure of CYCLODEXTRIN GLYCOSYLTRANSFERASE. This molecule has the UniProt identifier P43379 (CDGT2_BACCI)search. The sample contained 686 residues which is 100% of the natural sequence. Out of 686 residues 686 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.
