Figure 6.
HSQC NMR spectra of 15N-labeled tBID and BID61-104, free or bound to BCL-XL. (A) Free tBID (black) and free BID61-104 (red). Selected peaks from the loop and from the BH3 domain (boxes) are labeled. (B) BCL-XL-bound tBID (black) and BCL-XL-bound BID61-104 (red). (C) Free BID61-104 (black) and BCL-XL-bound BID61-104 (red); all peaks are labeled.
