Crystallographic analysis of an RNA polymerase σ-subunit fragment complexed with −10 promoter element ssDNA: quadruplex formation as a possible tool for engineering crystal contacts in protein–ssDNA complexes
Structural studies of −10 promoter element recognition by domain 2 of the RNA polymerase σ subunit [Feklistov & Darst (2011 ▶), Cell, 147, 1257–1269] reveal an unusual crystal-packing arrangement dominated by G-quartets. The 3′-terminal GGG motif of the oligonucleotide used in crystallization pa...
