Bacillus possesses the peptide toxin Sporulation-Delaying Protein(SDP),which can kill cells within a biofilm to support continued growth,thereby delaying the onset of biofilm sporulation.The four-component transporter YknWXYZ acts as a major SDP efflux pump to protect cells against the endogenous SDP toxin,for which YknYZ is a non-canonical ATP-binding cassette(ABC)-type transporter.
