Description

Photorhabdus is the only known terrestrial bioluminescent bacteria. Most members of the Photorhabdus are however insect pathogens that live in a strict symbiotic relationship within the digestive tract of entomopathogenic nematodes. Photorhabdus luminescens is a symbiont of nematodes and a broad-spectrum insect pathogen. It encodes a large number of adhesins, toxins, hemolysins, proteases and lipases, and contains a wide array of antibiotic synthesizing genes. These proteins likely play a role in the elimination of competitors, host colonization, invasion and bioconversion of the insect cadaver, making P. luminescens a promising model for the study of symbiosis and host-pathogen interactions (Ref.1). Glutathione metabolism in P. luminescens occurs within cells in two closely linked, enzymatically controlled reactions that utilize ATP and draw on [...]
