Predatory activity of Myxococcus xanthus outer-membrane vesicles and properties of their hydrolase cargo.

The deltaproteobacterium Myxococcus xanthus predates upon members of the soil microbial community by secreting digestive factors and lysing prey cells. Like other Gram-negative bacteria, M. xanthus produces outer membrane vesicles (OMVs), and we show here that M.
