The genomic content and context of auxiliary metabolic genes in marine cyanomyoviruses
Virology, 2016 Viruses of marine cyanobacteria frequently contain auxiliary metabolic genes (AMGs) that augment host metabolism during infection, but little is known about their adaptive significance. We analyzed the distribution and genomic context of 33 AMGs across 60 cyanomyovirus genomes.

Distinct Features of Cyanophage-encoded T-type Phycobiliprotein Lyase ΦCpeT: THE ROLE OF AUXILIARY METABOLIC GENES. [PDF]
J Biol Chem, 2017 Auxiliary metabolic genes (AMG) are commonly found in the genomes of phages that infect cyanobacteria and increase the fitness of the cyanophage. AMGs are often homologs of host genes, and also typically related to photosynthesis. For example, the ΦcpeT gene in the cyanophage P-HM1 encodes a putative phycobiliprotein lyase related to cyanobacterial T ...
