The binding interface between NlpI and Prc. a Domain organization of NlpI. The two TPR helices interacting with Prc are labeled in orange color. b Zoomed-in stereo view showing the interacting residues of NlpI (blue) and Prc (gold) in sticks. T2a/b and T3a indicate the TPR2a/b and TPR3a helices, respectively. c Sequence alignment of NlpI’s TPRs highlighting the acidic residues in TPR2b
