Functional domains of homoeologous PSY1 protein sequences. Amino acid sequences of PSY1 were analyzed using the NCBI’s Conserved Domain Database. Numbers above the alignment indicate the amino acid positions along the PSY-A1 protein. Framed, aspartate rich regions (DXXXD; substrate-Mg2+-binding sites); open black circle, substrate binding pocket; filled circle, catalytic residues; line, active site lid residues; blue circle, missense mutations; red circle, mutations resulting in significant yellow pigment content change, including truncation and missense mutations
