Gel filtration analysis of the drNurA-HerA complex formation. The drNurA-HerA mixture was analyzed with Superdex S200 HR 10/300 column. Input drHerA and drNurA were in a molar ratio of 2:1. Peaks of each injection were reconstructed using GraphPad Prism software. Fractions eluted were resolved by 12% SDS-PAGE. HerA m , HerA with point mutations D78A, E80A, and D81A; NurA m1 , NurA with point mutations H89A and R92A; NurA m2 , NurA with point mutations R117A, R121A, and H124A; NurA m3 , NurA with point mutations K299A, K303A, H305A, and K306A; NurA m4 , NurA with point mutations R336A, R337A, and R339A
