Physical and biochemical nature of the bacterial cytoplasm: movement and localization of mRNA and the 30S subunits of ribosomes
چکیده انگلیسی
There is a paucity of knowledge on how mRNA transcripts in the spatially crowded, but molecularly organized bacterial cytoplasm contact the 30S ribosomal subunits. Does simple diffusion in the cytoplasm account for transcript-ribosome interactions given that a large number of ribosomes (e.g., about 72,000 in Escherichia coli during exponential growth) can be present in the cytoplasm? Or are undiscovered mechanisms present where specific transcripts are directed to specific ribosomes at specific cytoplasmic locations, while others are mobilized in a random manner? Moreover, is it possible that cytoplasmic mobilization occurs in bacteria, driven possibly by thermal infrared (IR) radiation and the generation of exclusion zone (EZ) water? These aspects will be discussed in this article and hypotheses presented.
