Figure 3. Composition of ubiquitin and ubiquitin-like proteins within the genomes of four model eukaryotes and six medically important arthropod vectors.

Using HMMER v.3.0, complete sets of proteins for all ten genomes were scanned for the presence of five Pfam domain models for ubiquitin and ubiquitin-like proteins: APG12 (PF04110), Atg8 (PF02991), ubiquitin (PF00240), Ufm1 (PF03671), and Urm1 (PF09138). Only protein matches to Pfam models with E-values <0.05 were selected for compilations.
