1gp5 Summary


Anthocyanidin synthase from Arabidopsis thaliana complexed with trans-dihydroquercetin

The structure was published by Wilmouth, R.C., Turnbull, J.J., Welford, R.W.D., Clifton, I.J., Prescott, A.G., and Schofield, C.J., in 2002 in a paper entitled "Structure and Mechanism of Anthocyanidin Synthase from Arabidopsis Thaliana." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 2001.

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

The PDB entry contains the structure of LEUCOANTHOCYANIDIN DIOXYGENASE. This molecule has the UniProt identifier Q96323 (LDOX_ARATH)search. The sample contained 356 residues which is 100% of the natural sequence. Out of 356 residues 340 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.
