Figure 2.
Two-dimensional 15N-HSQC NMR spectra of Ca2+-free Tb24 recorded at 600 MHz proton frequency (A) and expanded view of spectrally crowded central region (B). Side chain amide resonances of Asn and Gln are connected with dotted lines. Representative resonance assignments are indicated and the complete list of assignments can be found at the BMRB repository (accession no. 18011).
