	% specific degradation*
	Exp. 1	Exp. 2	Exp. 3	Exp. 4	Mean ± SD
EBNA1	1.0	2.1	2.0	1.5	1.6  ±  0.4
E1-ΔGA	10.1	13.7	18.0	13.4	13.7  ±  3.3
% Inhibition†	90	85	89	88	88  ±  2
EBNA4	29.3	33.1	18.4	13.0	23.3  ±  8.7
E4-flGA	2.4	6.3	1.2	2.2	3.1  ±  2.1
% inhibition†	92	82	95	85	88  ±  6

^*Calculated as the difference between the % degradation detected in the presence or absence of ATP. 

^†Calculated as the ratio between the % specific degradation of Gly-Ala-containing and Gly-Ala-deleted polypeptides.
