CC   -!- FUNCTION: Negative regulator of phage lambda lysogenization.
CC       Contributes to the degradation of the phage regulatory protein CII.
CC       Acts probably by holding CII on the membrane surface, away from the
CC       target promoters, but close to the FtsH protease. {ECO:0000255|HAMAP-
CC       Rule:MF_00695}.
CC   -!- SUBUNIT: Interacts with CII protein from phage lambda.
CC       {ECO:0000255|HAMAP-Rule:MF_00695}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm. Cell inner membrane
CC       {ECO:0000255|HAMAP-Rule:MF_00695}; Peripheral membrane protein
CC       {ECO:0000255|HAMAP-Rule:MF_00695}; Cytoplasmic side {ECO:0000255|HAMAP-
CC       Rule:MF_00695}.
CC   -!- SIMILARITY: Belongs to the HflD family. {ECO:0000255|HAMAP-
CC       Rule:MF_00695}.
