'''STRUCTURE OF FUNCTIONALLY ACTIVATED SMALL RIBOSOMAL SUBUNIT AT 3.3 A RESOLUTION'''<br />

==Overview==
The small ribosomal subunit performs the decoding of genetic information, during translation. The structure of that from Thermus thermophilus shows, that the decoding center, which positions mRNA and three tRNAs, is, constructed entirely of RNA. The entrance to the mRNA channel will, encircle the message when a latch-like contact closes and contributes to, processivity and fidelity. Extended RNA helical elements that run, longitudinally through the body transmit structural changes, correlating, events at the particle's far end with the cycle of mRNA translocation at, the decoding region. 96% of the nucleotides were traced and the main fold, of all proteins was determined. The latter are either peripheral or appear, to serve as linkers. Some may assist the directionality of translocation.

==About this Structure==
1FKA is a [http://en.wikipedia.org/wiki/Protein_complex Protein complex] structure of sequences from [http://en.wikipedia.org/wiki/Thermus_thermophilus Thermus thermophilus] with WO2 as [http://en.wikipedia.org/wiki/ligand ligand]. The following page contains interesting information on the relation of 1FKA with [[http://pdb.rcsb.org/pdb/static.do?p=education_discussion/molecule_of_the_month/pdb10_1.html Ribosome]].
