GENERAL FEATURES AND BINDING OF METHOTREXATECRYSTAL STRUCTURES OF ESCHERICHIA COLI AND LACTOBACILLUS CASEI DIHYDROFOLATE REDUCTASE REFINED AT 1.7 ANGSTROMS RESOLUTION. I. GENERAL FEATURES AND BINDING OF METHOTREXATE

Structural highlights

3dfr is a 1 chain structure with sequence from Lacticaseibacillus casei. This structure supersedes the now removed PDB entry 1dfr. The October 2002 RCSB PDB Molecule of the Month feature on Dihydrofolate Reductase by David S. Goodsell is 10.2210/rcsb_pdb/mom_2002_10. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 1.7Å
Ligands:,
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

DYR_LACCA Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
