Insights into structure and function of 30S Ribosomal Protein S2 (30S2) in Chlamydophila pneumoniae: A potent target of pneumonia.

The gene 30S ribosomal protein S2 (30S2) is identified as a potential drug and vaccine target for Pneumonia. Its structural characterization is an important to understand the mechanism of action for identifying its receptor and/or other binding partners. The comparative genomics and proteomics studies are useful for structural characterization of 30S2 in C.

Background: The interaction between epithelial cells of endometrium and trophoblast cells during implantation is presumed to be accompanied by a change in gene expression in the cell types involved. The objective of this study was to identify such differentially expressed genes.
Methods: The interaction between the cell types was simulated in vitro by growing primary cell cultures of human endometrial epithelial cells and trophoblast cells together (co-culture) and separately (control cultures).
It has been shown in our previous study that mutations in genes relA, relC and rpsL result in the delay in Escherichia coli ilv operon derepression; the complete inhibition of derepression of the ilv operon is observed in the double mutants having alterations in rpsL and relA or relC genes. At present, some mutations occurring in the fus gene and altering the structure of the translational elongation G factor have been also found to delay derepression of E. coli ilv operon and complete inhibition in fusr and rel double mutants.

Biochim Biophys Acta
December 1978
We have described a mutant of Escherichia coli (designated 2S142) which shows specific inhibition of rRNA synthesis at 42 degrees C. ppGpp levels increase at the restrictive temperature, as expected. However, when the cells are returned to 30 degrees C, rRNA synthesis resumes before ppGpp levels have returned to normal.

February 1976
S. typhimurium mutants with altered sensitivity to fusidic acid (more resistant or more sensitive than the original culture) were selected. The mutants studied changed some of their properties (morphology, antigenic structure, and biochemical activity).
