Purification of GAF-DBD protein. a, Subtractive Ni-NTA purification after “one-pot” reaction where 6xHis-SUMO was cleaved off and the N-terminal cysteine is exposed and labeled with Cy3. The calculated molecular weights are 34.4 kDa for 6xHis-SUMO-Cys-GAF-DBD, 21.0 kDa for Cys-GAF-DBD and 13.4 kDa for 6xHis-SUMO. b, Schematics of full-length GAF short isoform, GAF-DBD and NURF-binding regions62 to scale.
