Structure analysis suggests Ess1 isomerizes the carboxy-terminal domain of RNA polymerase II via a bivalent anchoring mechanism
Namitz, Zheng et al. identify a bivalent interaction by the yeast Ess1 with CTD peptides of RNA polymerase II. Their results suggest an anchored mechanism of isomerization, and raise the possibility of eukaryotic parvulin-class prolyl isomerases gaining a broader substrate specificity during evoluti...

| Sumario: | Namitz, Zheng et al. identify a bivalent interaction by the yeast Ess1 with CTD peptides of RNA polymerase II. Their results suggest an anchored mechanism of isomerization, and raise the possibility of eukaryotic parvulin-class prolyl isomerases gaining a broader substrate specificity during evolution, by acquiring a flexible linker that generates a more dynamic binding mode. |
