ジャーナル: Acta Crystallogr.,Sect.F / 年: 2005 タイトル: Two crystal structures of dihydrofolate reductase-thymidylate synthase from Cryptosporidium hominis reveal protein-ligand interactions including a structural basis for observed antifolate resistance. 著者: Anderson, A.C.
This entry contains the crystallographic asymmetric unit which consists of 5 chains. The biological unit is a dimer. Chains A,B and C,D form two dimers. Chain E is on a crystallographic two-fold, its monomer partner is formed across this two-fold.
