TROSY HSQC spectrum of deuterated CaMK1D at 1.2 mM concentration in 50 mM Na phosphate pH 7, 75 mM NaCl, 0.5 mM TCEP, 0.02% NaN₃ collected at 298 K on a 800 MHz Varian Inova spectrometer. The blue box (denoted A) is an expansion of the crowded central region of the spectrum. The red box (denoted B) further expands the congested central region. Backbone HN peaks are labeled with their assignments. Trp sidechain HN groups are indicated by W-sc. Green boxes highlight examples of residues exhibiting more than one conformation
