3i8h Summary

pdbe.org/3i8h
spacer

Elongation complex of the 70S ribosome with three tRNAs and mRNA.This entry 3I8H contains 30S ribosomal subnit. The 50S ribosomal subunit can be found in PDB entry 3I8I. Molecule A in the same asymmetric unit is deposited as 3I8F (50S) and 3I8G (30S).

The structure was published by Jenner, L.B., Demeshkina, N., Yusupova, G., and Yusupov, M., in 2010 in a paper entitled "Structural aspects of messenger RNA reading frame maintenance by the ribosome." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.1 Å and deposited in 2009.

The experimental data on which the structure is based was also deposited.

This entry contains 3278 copies of 23 unique biopolymers (complete list).

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The most likely quaternary structure is a 26meric assembly.
