Conformational exchange rates for selective residues in binase^*

Residue	Conformational exchange rate, s−1
Gln-28	3.8  × 103 ± 600
Phe-55	2.4  × 103 ± 1,200
Trp-70	2.7  × 103 ± 200
Leu-97	2.7  × 103 ± 700
Tyr-102	4.7  × 103 ± 800
Ala-103	6.1  × 103 ± 1,200

^*The data were obtained by measuring the apparent ¹⁵N R₂ relaxation rate as a function of the CPMG repetition rate.
