==THYMIDYLATE SYNTHASE FROM RAT IN TERNARY COMPLEX WITH DUMP AND TOMUDEX==
-
Two crystal structures of rat thymidylate synthase (TS) complexed with, dUMP and the anticancer drug Tomudex (ZD1694) have been determined to, resolutions of 3.3 and 2.6 A. Tomudex is one of several new antifolates, targeted to TS and the first to be approved for clinical use. The, structures represent the first views of any mammalian TS bound to ligands, and suggest that the rat protein undergoes a ligand-induced conformational, change similar to that of the Escherichia coli protein. Surprisingly, Tomudex does not induce the "closed" conformation in rat TS that is seen, on binding to E. coli TS, resulting in inhibitor atoms that differ in, position by more than 1.5 A. Several species-specific differences in, sequence may be the reason for this. Phe 74 shifts to a new position in, the rat ... [[http://ispc.weizmann.ac.il/pmbin/getpm?9894005 (full description)]]
