Left: Experimental (black solid lines) and simulated (red dotted lines) ¹⁵N σ₁-CSA line shapes of U-[¹³C, ¹⁵N]-Tyr HIV-1 C-terminal domain (CTD) of CA protein recorded by R8₁³ sequence. Right: Experimental (black solid lines) and simulated (red dotted lines) ¹⁵N CSA line shapes of the same sample recorded by ROCSA sequence. The sample was spun at the MAS frequency of 10 kHz. The best-fit CSA parameters are shown for each Tyr residue.
