CC -!- FUNCTION: Required for dimerization of active 70S ribosomes into 100S
CC ribosomes in stationary phase; 100S ribosomes are translationally
CC inactive and sometimes present during exponential growth.
CC {ECO:0000256|HAMAP-Rule:MF_00839}.
CC -!- SUBUNIT: Interacts with 100S ribosomes. {ECO:0000256|HAMAP-
CC Rule:MF_00839}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00839}.
CC -!- SIMILARITY: Belongs to the HPF/YfiA ribosome-associated protein family.
CC Long HPF subfamily. {ECO:0000256|HAMAP-Rule:MF_00839}.
