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. CC -!- SUBUNIT: Homotrimer. CC -!- SIMILARITY: Belongs to the RapZ-like family. RapZ subfamily. else CC -!- FUNCTION: Displays ATPase and GTPase activities. CC -!- SIMILARITY: Belongs to the RapZ-like family. end case XX DR Pfam; PF03668; ATP_bind_2; 1; trigger=no DR PIRSF; PIRSF005052; P-loopkin; 1; trigger=no XX case KW RNA-binding end case KW ATP-binding KW GTP-binding KW Nucleotide-binding XX GO GO:0005524; F:ATP binding GO GO:0005525; F:GTP binding XX FT From: RAPZ_ECOLI (P0A894) FT BINDING 8..15 FT /ligand="ATP" FT /ligand_id="ChEBI:CHEBI:30616" FT Condition: G-x(2)-G-[SAG]-G-[KR]-x FT BINDING 56..59 FT /ligand="GTP" FT /ligand_id="ChEBI:CHEBI:37565" FT Condition: D-x-R-x case FT REGION 266..Cter FT /note="RNA-binding" end case XX Size: 261-372; Related: None; Template: O06973; P0A894; Scope: Bacteria Fusion: Nter: None Cter: None Duplicate: None Plasmid: None Comments: Homologs of RapZ are present in a wide range of bacteria indicating an important function. However, in bacteria that do not possess sRNAs GlmY and GlmZ, the role of RapZ homologs remains elusive. (see PubMed:24667238) XX # Revision 1.35 2022/11/19 //
