Schematic Representation of Functional Features of the V. litorea PRK Protein Imposed Upon the Corresponding Gene Organization.

Five exons enclosed in brackets (I–V) and four introns represented by black boxes (i–iv) illustrate the genomic structure. Numbered amino acid residues are shown below the corresponding genomic segments. The hatched box represents the plastid transit peptide sequence within exon 1, corresponding to amino acids 1–42. The gray shaded boxes represent the PRK domain sequence, corresponding to amino acids 62–266, and spanning much of exon II, all of exon III, and 24 bp of exon IV.
