Rat1/Rai1 does not have ATPase activity. (A) ATPase activity assay of Rat1/Rai1. Calf intestinal phosphatase (CIP), SV40 T antigen (T ag) and Xrn1 were used as controls. Highly purified Rat1/Rai1 fractions from size-exclusion chromatography (Superose 6) show no ATPase activity. (B) Quantification of the remaining RNAs from the in vitro transcription termination assay with various non-hydrolyzable ATP analogs.
