Isolation of Ribosomal Particles from the Unicellular Cyanobacterium Synechocystis sp. PCC 6803

Description

Isolation of ribosomal particles is an essential step in the study of ribosomal components as well as in the analysis of trans-acting factors that interact with the ribosome to regulate protein synthesis and modulate the expression profile of the cell in response to different environmental conditions. In this protocol, we describe a procedure for the isolation of 70S ribosomes from the unicellular cyanobacterium Synechocystis sp. PCC 6803 (hereafter Synechocystis). We have successfully used this protocol in our study of the cyanobacterial ribosomal-associated protein LrtA, which is a homologue of bacterial HPF (hibernation promoting factor) (Galmozzi et al., 2016).
