Promoter Fragments Targeted by SHI/STY Family Proteins Show Sequence Similarities.

(A) and (B) Asterisks indicate identical residues; one and two dots indicate different degrees of similarity.

(A) Protein alignment of STY1 and a C. roseus ortholog (ABL63114.1). A gray box marks the RING-like zinc finger domain.

(B) Promoter fragments with affinity to SHI/STY family members. A black box marks the mutated residues in the YUC4mut2_pro:HIS3 construct. Dark gray boxes mark the base pairs mutated in the ORCA3 promoter (vom Endt et al., 2007).
