===BACTERIOPHAGE GA PROTEIN CAPSID===

~~==Overview==~~

<!--

The ~~three-dimensional structure of~~ the ~~small T=3 RNA bacteriophage GA has been determined~~ at 3.~~4 A resolution~~. ~~The structure was solved by molecular replacement~~, ~~using~~ the ~~phage MS2 as an initial model~~. A comparison of the protein shells of the four related phages GA, MS2, fr and Qbeta was carried out in order to define structural features of particular importance for their assembly and specific RNA interaction. A high degree of similarity was found in the RNA binding sites, whereas larger structural differences are located in the loop regions of the coat proteins, especially in the FG loops forming 5-~~fold and quasi~~-6-fold contacts. The overall arrangement of the protein subunits in the shells of these phages is very similar, although the details of the interactions differ. The few conserved interactions are suggested to govern the subunit packing during assembly.

The line below this paragraph, {{ABSTRACT_PUBMED_9299325}}, adds the Publication Abstract to the page

(as it appears on PubMed at http://www.pubmed.gov), where 9299325 is the PubMed ID number.
