Ta Bank (PDB) with accession code A. Protein NA modelling and structure analysisProtein purification For lysis g of kLANA cell pellets had been resuspended in Gly-Pro-Arg-Pro acetate icecold buffer A (mM NaK Phosphate, mM NaCl, (vv) glycerol, M NDSB, pH .) supplemented with mgml lysozyme, unitml OmniCleave (epicentre) and one total EDTAfree protease inhibitor cocktail tablet (Roche) per ml of resuspended cells, and incubated for min at C. Cells have been lysed additional working with a Z Fundamental cell disruptor (Constant Systems Ltd). The lysate was cleared by centrifugation at g for min at C. All the purification steps were performed applying an AKTA Explorer FPLC Technique at area temperature (GE Healthcare). The supernatant was passed by means of GSTPrepTM FF column using a peristaltic P pump at C (GE Healthcare). The column was then washed with buffer A and eluted with buffer B (mM NaK phosphate, mM NaCl, (vv) glycerol, mM glutathione, pH . (C)). The principle fractions were pooled and C protease was added in a molar ratio to GSTtagged kLANA protein with an addition of mM DTT and mM EDTA. The cleaved GST and unspecific DNA were removed from kLANADBD by further passing by means of HiPrepTM Heparin FF column (GE Healthcare). The column was washed with buffer A and eluted using a linear gradient with buffer C (mM NaK Phosphate, mM NaCl, pH . at C). The protein was eluted about mM NaCl as well as the fractions were pooled, concentrated and injected into HiLoadTM SuperdexTM pg column (GE Healthcare) which was pre equilibrated with buffer D (mM NaK phosphate, mM NaCl, glycerol pH . at C).

The kLBS and mLBS DNA models had been prepared utilizing DDART web server . The protein interfaces and interaction surfaces have been calculated and analyzed utilizing the PISA webserver . Structural evaluation was performed and figures ready utilizing PyMOL. Bend and rotation angles have been calculated utilizing the pymol draw rotation axis and angle involving helices scripts, respectively. Smallangle Xray scattering (SAXS) The synchrotron radiation Xray scattering data from options of totally free kLANA DBD, mLANA DBD, LBS DNA of KSHV and MHV and from their complexes were collected on the P beamline in the EMBL on the PETRAIII storage ring (DESY, Hamburg, Germany) and in the ESRF BM beamline (Grenoble, France) . SPDP site Measurements at the P and BM beamlines have been performed applying PILATUS detector and automated filling . Information acquisition was performed at a sampledetector distance of . m, covering the range of momentum transfer . s . nm (s sin where may be the scattering angle and . nm could be the Xray wavelength) in frames of . ms to verify for probable radiation damage. The data had been normalized for the intensity from the transmitted beam and radially averaged; the scattering with the buffer was subtracted and the distinction curves have been scaled for solute concentration. Main information reduction was performed by automated pipeline and complete analysis on the scattering profiles was accomplished utilizing the ATSAS software program package . The forward scattering I plus the radii of gyration Rg were evaluated using the Guinier approximation, assuming that at really modest angles (s .Rg), the Nucleic Acids Analysis, , VolNo.intensity
