YCF1 Structural Features and Charge Distribution.

Structure and charge distribution of exemplary YCF1 proteins of eight species (i to viii). Proteins are schematically drawn, but to scale with regard to their amino acid length (scale at the top) based on current genome annotations. Potentially problematic annotations (red question marks) include a possibly incorrect open reading frame annotation (sequence ii), a frameshift (possible sequencing error; sequence iii), and an overlooked potential intron (sequence iv). ATCG01000 is a truncated copy of YCF1 present in the inverted repeat of the Arabidopsis plastid genome. Positive and negative charge distribution is shown in green and red, respectively, based on EMBOSS charge prediction using the standard settings. The positions of TMHMM-predicted TM helices are highlighted by yellow boxes. For each protein the gene ID or NCBI accession is shown at the C terminus of the respective sequence.
