Crystal structure of human orotidine 5'-monophosphate decarboxylase complexed with CMP-N4-OH

The structure was published by Purohit, M.K., Poduch, E., Wei, L.W., et al., Kain, K.C., Pai, E.F., and Kotra, L.P., in 2012 in a paper entitled "Novel cytidine-based orotidine-5'-monophosphate decarboxylase inhibitors with an unusual twist." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 2012.

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

This PDB entry contains multiple copies of the structure of Uridine 5'-monophosphate synthase.

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.
