Binding stoichiometry of NP-UAP56 complex. (a) SDS-PAGE analysis. The detail of purification scheme is described in Methods. Lane 1, molecular size marker; Lane 2, NP-His; Lane 3, UAP56. (b) Gel filtration chromatography. NP-UAP56 complex was partially purified using Sephacryl S-200 gel filtration column. Then, the purified NP-UAP56 complex (black), UAP56 (red), and NP (blue) were eluted from a Superose 6 gel filtration column. The peak positions of protein standards are marked by arrows. (c) NP (300 ng), UAP56 (300 ng), and NP-UAP56 complex (66, 200, and 600 ng) were separated on 10% SDS-PAGE and visualized by CBB staining. (d) UAP56, NP, and NP-UAP56 complex were analyzed by 6% native PAGE in 0.5 × TBE buffer and visualized by silver staining.
