Peptidyl-prolyl cis-trans isomerase ESS1

Gene

ESS1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Essential PPIase specific for phosphoserine and phosphothreonine N-terminal to the proline residue. Required for efficient pre-mRNA 3'-end processing and transcription termination, probably by inducing conformational changes by proline-directed isomerization in the C-terminal domain (CTD) of RPB1, thereby altering cofactor binding with the RNA polymerase II transcription complex. Also targets the SIN3-RPD3 histone deacetylase complex (HDAC).

Miscellaneous

Present with 4401 molecules/cell in log phase SD medium.1 Publication

Catalytic activityi

Peptidylproline (omega=180) = peptidylproline (omega=0).1 Publication

Enzyme regulationi

Inhibited by 5-hydroxy-1,4-naphthoquinone (juglone), but not by FK506 or cyclosporin A.1 Publication
