CC   -!- FUNCTION: Modulates the synthesis of GlmS, by affecting the processing
CC       and stability of the regulatory small RNA GlmZ. When glucosamine-6-
CC       phosphate (GlcN6P) concentrations are high in the cell, RapZ binds GlmZ
CC       and targets it to cleavage by RNase E. Consequently, GlmZ is
CC       inactivated and unable to activate GlmS synthesis. Under low GlcN6P
CC       concentrations, RapZ is sequestered and inactivated by an other
CC       regulatory small RNA, GlmY, preventing GlmZ degradation and leading to
CC       synthesis of GlmS. {ECO:0000255|HAMAP-Rule:MF_00636}.
CC   -!- SUBUNIT: Homotrimer. {ECO:0000255|HAMAP-Rule:MF_00636}.
CC   -!- SIMILARITY: Belongs to the RapZ-like family. RapZ subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_00636}.
