H/D exchange half-life values (in min) of populations of hydrogens of WALP16 and WALP16(+10), calculated from logarithmic plots of the data in Fig. 3 (see text for details)

	WALP16		WALP16(+10)
	No. of hydrogens	Half-life, min	No. of hydrogens	Half-life, min
Fast	6	≤3	15	≤2
Intermediate	1.5	1.4  × 101	2	1.9  × 101
	2	2.4  × 102	2	7.0  × 101
	2	3.4  × 103	2	3.5  × 102
Slow	10	1.8  × 104	10	2.3  × 104

Fast exchange was defined as between 0 and 2 min, intermediate exchange from 2–1,000 min and slow exchange starting from about 1,000 min. The number of hydrogens in each population is indicated (estimated errors in these numbers are in all cases 0.5).
