Ubiquitin proteins in Bigelowiella natans (a) and Guillardia theta (b). The length of schematic bars shown are proportional to protein length, where a ubiquitin monomer indicates 76 amino acids. In the case of polyubiquitin, multiple polyubiquitin-encoding genes exist in both genomes, with different numbers of ubiquitin monomers [ranging from 1.5 monomers (‘× 1.5’) to 4 monomers (‘× 4’)]. A total of 7 and 11 polyubiquitin genes were found in B. natans and G. theta, respectively. Ubiquitin moieties are shown in orange; the various ubiquitin fusion partners found in the B. natans and G. theta genomes are colored and labeled accordingly (see Tables 1 and 2 for more information)
