Spatial specialization of antioxidant defenses dictates predation success in Myxococcus xanthus
Redox-based chemical warfare is a primary driver of microbial community assembly. Here, we show that the predatory bacterium Myxococcus xanthus employs a spatial division of labor between two inducible monofunctional catalases, mxKatB and mxKatE, to overcome prey-derived hydrogen peroxide (H₂O₂). Quantitative transcrip...
