Table 1. A summary of quantitative estimation of secondary structural elements of the GR AF1 and TBP before and after complex formation.

Spectrum	Helix, %	Sheet, %	Bend, %	Turn, %	Coil, %
AF1	26.7	11.6	10.0	12.3	39.4
AF1:TBP-TBP	42.1	11.8	9.3	12.4	24.4
TBP	41.3	16.1	9.4	12.4	20.8
AF1:TBP-AF1	41.0	16.4	9.6	12.4	20.6

The data are calculated from second-derivative FTIR spectra. AF1:TBP-TBP indicates the secondary structures attributable to AF1 in the AF1:TBP complex, after removal of the contributions of TBP; and AF1:TBP-AF1 indicates the structures of TBP in the complex after removal of the contribution of AF1.
