CHALCONE SYNTHASE FROM ALFALFA COMPLEXED WITH NARINGENIN

The structure was published by Ferrer, J.L., Jez, J.M., Bowman, M.E., Dixon, R.A., and Noel, J.P., in 1999 in a paper entitled "Structure of chalcone synthase and the molecular basis of plant polyketide biosynthesis." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.84 Å and deposited in 1999.

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

The PDB entry contains the structure of PROTEIN (CHALCONE SYNTHASE). This molecule has the UniProt identifier P30074 (CHS2_MEDSA)search. The sample contained 389 residues which is 100% of the natural sequence. Out of 389 residues 387 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 most likely forms homodimers.
