Fig. 4. AMGs in viruses under the Ross Ice Shelf.

Abundant viral AMG are depicted including the information of potential hosts. Some of the detected viral AMG belong to very abundant and active viruses that infect some of the most abundant and active chemolithoautotrophic bacteria contributing to primary production under the Ross Ice Shelf according to Martínez-Pérez and colleagues⁵. 3D-structure protein prediction was made for some AMG involved in sulfur transportation. Notice that the 3D structure of the homolog viral protein and that of the host are quite similar. Prediction was performed with Alphafold. For more details, see confident values from Alphafold 3D prediction in Fig. S3.
