Not long ago, Elio said in this blog that predation, a major force in evolution, is somewhat neglected in microbiological circles. The full implications of predation are just beginning to be uncovered as more becomes known about the ecology, physiology, and genomics of predators against microbes and their interactions with their prey. The collective knowledge of how they influence each other will naturally feed curiosity of scientists regarding how some cellular characteristics evolved. Here, I address a new metabolic feature of a predatory bacterium that will certainly lend itself to evolutionary considerations.
