Peptide controlling LiaRS; Suggested to be the precursor for an exported, modified peptide that has antimicrobial and/or signaling properties. Synthesis requires YydG and YydH; the peptide is proposed to be exported by the YydIJ transporter. In the absence of the transporter, the modified peptide activates the LiaRS two-component regulatory system, possibly by eliciting cell envelope stress. This activation can occur in trans in cocultured cells lacking either the transporter or the whole operon.

ABC transporter (ATP-binding protein); Suggested to be part of an ABC transporter complex YydIJ involved in export of the modified peptide YydF (Probable). Responsible for energy coupling to the transport system (By similarity).

Putative permease for export of a regulatory peptide; Suggested to be part of an ABC transporter complex YydIJ involved in export of the modified peptide YydF.

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 [...]

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.

Exporter of killing factor SpbC; Required for the maturation of SdpC to SDP. Not required for SdpC signal peptide cleavage, secretion from the cell or disulfide bond formation.

Spore photoproduct (thymine dimer) lyase; Involved in repair of UV radiation-induced DNA damage during spore germination. Can repair thymine dimer 5-thyminyl-5,6- dihydrothymine (known as spore photoproduct (SP)) by in situ monomerization of SP to two thymines.

Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.

Putative acetyltransferase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
