Fig. 2From: Genome-wide identification, evolutionary and functional analyses of KFB family members in potatoThe tertiary structures of Kelch motifs with different numbers. a A typical Kelch motif with a four-stranded β-sheets. b-g The tertiary structures of Kelch domains with 1–6 Kelch motifs predicted by SWISS-MODEL website. The Kelch domains were extracted from StKFB07, StKFB02, StKFB03, StKFB01, StKFB09 and StKFB27, respectivelyBack to article page
