^aViromes were concentrated and purified using different protocols as described by Hurwitz et al. [26].
^bCarbon metabolism genes (see Additional file 5: Table S3) were detected in viral and microbial metagenomes derived from the same water sample taken from Scripps Pier in San Diego, CA in April 2009.
^cCarbon metabolism genes were considered to be detected if they had more than 5 normalized read hits.
