The L17 ribosomal protein of Bacillus subtilis binds preferentially to curved DNA
1Institut de Génétique et Microbiologie, Université Paris-Sud, Orsay, France.
Abstract:
We searched in Bacillus subtilis for proteins that bind preferentially to curved DNA. Two proteins of 9 and 15 kDa displaying this property were purified from exponentially growing cells of B. subtilis strain 168. Sequencing of N-terminal amino acids identified them as the proteins HBsu and L17 respectively. The overproduction of L17 from B. subtilis in Escherichia coli was shown to have a strong effect on nucleoid morphology and segregation.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
