CC -!- FUNCTION: Is an L-glutamate ligase that catalyzes the ATP-dependent
CC post-translational addition of glutamate residues to the C-terminus of
CC ribosomal protein S6 (RpsF). Is also able to catalyze the synthesis of
CC poly-alpha-glutamate in vitro, via ATP hydrolysis from unprotected
CC glutamate as substrate. The number of glutamate residues added to
CC either RpsF or to poly-alpha-glutamate changes with pH.
CC {ECO:0000255|HAMAP-Rule:MF_01552}.
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01552};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01552};
CC Note=Binds 2 magnesium or manganese ions per subunit.
CC {ECO:0000255|HAMAP-Rule:MF_01552};
CC -!- SIMILARITY: Belongs to the RimK family. {ECO:0000255|HAMAP-
CC Rule:MF_01552}.
