| sdpA | skfA | BSU33750 | BSU01910 | Export of killing factor; Required for the maturation of SdpC to SDP. Not required for SdpC signal peptide cleavage, secretion from the cell or disulfide bond formation. | Sporulation killing factor A; Produces a 26-residue extracellular sporulation filling factor (SKF) that induces the lysis of other B.subtilis cells that have not entered the sporulation pathway, providing a source of nutrients to support sporulation, and at the same time delaying commitment to the energetically expensive and irreversible onset of sporulation. Can also inhibit growth of other bacteria at high concentrations. Addition of SKF to solid cultures induces killing, but it is much less effective than SDP (AC O34344).

Not required for SdpC signal peptide cleavage, secretion from the cell or disulfide bond formation. | Synthesis of sporulation killing factor A; Catalyzes the formation of the thioether bond required for production of the sporulation killing factor (SKF) from SkfA. Forms the cysteine-methionine thioether bond found in SKF; the acceptor amino acid can be hydrophobic, aromatic or a small hydrophilic amino acid but not a larger hydrophilic amino acid, i.e. Met=Ala, Phe, Leu, Tyr>Asn, Ser>>Gln, Glu, Lys. The relative position of Cys and Met in the substrate cannot be inverted, in vitro the thioether bond cannot be made in the absence of the SkfA propeptide, suggesting this is the first rea [...] | 0.525 |
