TABLE 1.

Infectivity of full-length RNA transcripts correlates with Arf activation by 3CD

3CD amino acid 441 (codon)	% of Arf activation by 3CDa	Full-length RNA specific infectivity	Position 441 reversion (codon)
F (TTC) (wt)	100	wt	NAb
Y (TAC)	86	wt	NA
I (ATT)	71	wt	NA
L (TTA)	60	wt	NA
S (TCC)	9	Quasi-infectious	F (TTC)
S (TCA)	NDc	Quasi-infectious	L (TTA)
A (GCA)	35	Quasi-infectious	F (TTC)
R (AGA)	4	Quasi-infectious	I (ATA)
E (GAA)	1	Quasi-infectious	V (GTA)

^aThe percentage of Arf activation was quantitated by analyzing the Arf immunoblot image with Total Lab 1D software.

^bNA, not applicable.

^cND, not determined.
