NUCLEIC ACIDS RES. 41 7815 7827 2013 23804759 doi:10.1093/nar/gkt560 Holoenzyme complex of Thermus thermophilus DNA gyrase with ADPNP Holoenzyme complex of Thermus thermophilus DNA gyrase with ADPNP
monodisperse complex formed in presence of ADPNP
dimer 1 0.321 0.321 native mass spectrometry DNA gyrase Thermus thermophilus 0.321 0.321
The two subunits of the DNA gyrase were fused for structural stability. ADPNP (non hydrolysable analog of ATP) was added to form the holoenzyme complex. This complex was crosslinked with glutaraldehyde prior to vitrification.
