'''Ribosomal Protein L10-L12(NTD) Complex, Space Group P212121, Form B'''<br />


==Overview==
==Ribosomal Protein L10-L12(NTD) Complex, Space Group P212121, Form B==
The L7/12 stalk of the large subunit of bacterial ribosomes encompasses, protein L10 and multiple copies of L7/12. We present crystal structures of, Thermotoga maritima L10 in complex with three L7/12 N-terminal-domain, dimers, refine the structure of an archaeal L10E N-terminal domain on the, 50S subunit, and identify these elements in cryo-electron-microscopic, reconstructions of Escherichia coli ribosomes. The mobile C-terminal helix, alpha8 of L10 carries three L7/12 dimers in T. maritima and two in E., coli, in concordance with the different length of helix alpha8 of L10 in, these organisms. The stalk is organized into three elements (stalk base, L10 helix alpha8-L7/12 N-terminal-domain complex, and L7/12 C-terminal, domains) linked by flexible connections. Highly mobile L7/12 C-terminal, domains promote recruitment of translation factors to the ribosome and, stimulate GTP hydrolysis by the ribosome bound factors through, stabilization of their active GTPase conformation.

== Function ==
[https://www.uniprot.org/uniprot/RL10_THEMA RL10_THEMA] Forms part of the ribosomal stalk, playing a central role in the interaction of the ribosome with GTP-bound translation factors (such as IF-2, EF-Tu, EF-G and RF3) (Probable).[HAMAP-Rule:MF_00362]
