A phospholipase B effector exploits membrane lipid divergence to drive inter-Bacteroides competition and enables universal genome editing
ABSTRACT The Type VI secretion system (T6SS) mediates interbacterial competition, yet the mechanisms underlying its effector diversity and cell-targeting specificity remain poorly understood. Here, we identify Btle, a phospholipase B (PLB) effector defining a unique Tle subfamily (Tle7), encoded in approximately 18.0%...
