CC   -!- ALTERNATIVE PRODUCTS:
CC       Event=Alternative initiation; Named isoforms=2;
CC       Name=YbiX;
CC         IsoId=P0DSH3-1; Sequence=Displayed;
CC       Name=Ybix-S;
CC         IsoId=P0DSH3-2; Sequence=VSP_060150;
CC   -!- INDUCTION: The YbiX-S short isoform is expressed in both exponential
CC       and stationary phase in rich medium; expression is higher during
CC       exponential phase (at protein level). The YbiX long isoform seems only
CC       to be expressed in exponential phase at low levels (at protein level).
CC       {ECO:0000269|PubMed:30837344}.
CC   -!- MISCELLANEOUS: Encoded antisense to waaL; both isoforms are encoded
CC       within the waaL gene. {ECO:0000269|PubMed:30837344}.
