Alexa Fitzpatrick (University of Toronto) and colleagues published a new paper on phage reprogramming of bacterial metabolism, showing two phage proteins increase amino acid and putrescine levels in Pseudomonas aeruginosa to promote efficie

Tetrapyrroles such as heme, chlorophyll, and vitamin B12 are essential for various metabolic pathways. Helen Wegner (University of Kaiserslautern-Landau, Germany) and colleagues demonstrated the presence of tetrapyrrole genes in phage seque

A new paper in PNAS by Bin Li and colleagues discusses how viruses require the small polyamine spermidine to replicate normally, in part due to its important role in ribosomal translation. They found genes in many phages and eukaryotic viru
