Comparison of the Kelch domains of NS1-BP and its homologues. (a, b) Superposition of the Kelch domain of NS1-BP (grey) on those of KEAP1 (PDB entry 1zgk; magenta) and KBTBD (PDB entry 4asc; cyan). The six Kelch repeats are numbered 1–6. The comparison highlights the differences in the B–C loop regions. (c) Structure-based sequence alignment of the second and the sixth Kelch-repeat motifs from the Kelch domains of NS1BP, KEAP1 and KBTBD5. Conserved regions are shown in blue boxes. Highly conserved residues are in white on a red background; moderately conserved residues are in red. Sequence alignment was performed using ESPript (Robert & Gouet, 2014). |
