== Function ==
[https://www.uniprot.org/uniprot/RIMK_ECOLI RIMK_ECOLI] Responsible for the addition of glutamate residues to the C-terminus of ribosomal protein S6.

== Publication Abstract from PubMed ==
We report herein the crystal structure of E. coli RimK at 2.85 A resolution, an enzyme that catalyzes the post-translational addition of up to fifteen C-terminal glutamate residues to ribosomal protein S6. The structure belongs to the ATP-grasp superfamily and is organized as a tetramer, consistent with gel filtration analysis. Each subunit consists of three distinct structural domains and the active site is located in the cleft between these domains. The catalytic reaction appears to occur at the junction between the three domains since ATP binds between the B and C domains, and other substrates bind nearby. (c) Proteins 2013;.
