Table 1.

Sequences of the lead peptides L-22 and KP-Z-41 and summary of their binding activities against HIV-1 TAR RNA (K_d values are in nanomolar), as determined by EMSA in the absence of competitor tRNA

Mimetic			Residue														Kd (HIV)
L-22			R1	V2	R3	T4	R5	K6	G7	R8	R9	I10	R11	I12			30
KP-Z-41	R1	V2	R3	C4	R5	Q6	R7	K8	G9	R10	R11	I12	C13	I14	R15	I16	1

Residues are aligned in the table to represent similarity in position upon binding HIV-1 TAR.
