Predicted domain architecture of D. discoideum PPR proteins, PtcA-L.

Abstract

<p>Blue boxes represent PPR motifs. The amino acid length of each protein is indicated at the C-terminus of each protein. Also displayed are the putative tRNA methyltransferase (yellow), MATH-like (green), and ubiquitin hydrolase-like (orange) domains of PtcE, PtcJ, and PtcK, respectively.</p
