Purification of GAF-DBD protein. a, Subtractive Ni-NTA purification after “one-pot” reaction which cleaved off 6xHis-SUMO and labeled the N-terminus of GAF-DBD 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 GAF-FL short isoform, GAF-DBD and NURF-binding regions (PMID 11583616) to scale. c, Native hsp70 promoter DNA sequence. GAF cognate sites are highlighted in red. TATA box in bold.
