Researchers found a single gene involved in iron-sulphur clusters crucial for TB bacterium's persistence. The IscS gene helps regulate the SUF operon, preventing hypervirulence and allowing the bacteria to survive harsh lung conditions.
Researchers at Texas A&M University have developed a computational tool to study complex units of clustered genes called operons in bacteria. The tool allows scientists to analyze many bacterial genomes at once and is more accurate than previous methods.
Researchers have determined the life cycle of operons, small groups of genes with related functions co-transcribed in a single strand of messenger RNA. The findings reveal that operon creation and destruction lead to large changes in gene expression patterns, suggesting adaptation to environmental stresses.
Researchers at Cold Spring Harbor Laboratory have discovered that Spot 42, a small RNA, differentially regulates gene expression in the E. coli galactose operon through an antisense mechanism. The study provides mechanistic insight into the process and answers long-standing biological questions.
