Fig. 2From: A novel group of diverse Polinton-like viruses discovered by metagenome analysisGenome architectures of the Polinton-like viruses: genomic contigs extracted and assembled from metagenomes, the PgVV-like group. Tlr1 helicase, a superfamily 1 helicase similar to the helicase encoded by the Polinton-like element Tlr1 from Tetrahymena. The other designations and color coding are the same as in Fig. 1 Back to article page
