WebThe Bacillus subtilis ilv-leuoperon is involved in the biosynthesis of branched-chain amino acids. This operon exhibits a RelA-dependent positive stringent response to amino acid starvation. We investigated this positive stringent response upon lysine starvation as well as decoyinine treatment.
WebJan 9, 2006 · The leu operon, which includes only genes for the leucine synthesis, is predicted to be regulated by attenuation in some γ-proteobacteria (Enterobacteria, Pasteurellales, Vibrionales, Alteromonadales, and Xanthomonadales), but not in Pseudomonadales and other species. WebMar 25, 2024 · The ilv-leu operon is an important operon that is directly involved in the biosynthesis of branched chain amino acids (BCAAs), a precursor of bioalcohols in B. subtilis. This operon has a positive stringent response according to amino acid starvation and is dependent on the regulatory proteins such as RelA regulator . The regulation of …
WebSep 22, 2003 · The ilv-leu operon is the third example of a polycistronic operon in B. subtilis exhibiting modulation of the amounts of its encoded proteins by mRNA processing and differential segmental mRNA stability. Besides regulation of the whole operon via CodY repression and T-box-mediated antitermination, ... WebOur results indicate that the ilv-leu operon might be the only genetic locus involved in branched-chain amino acid biosynthesis which depends on a functional CcpA for full …
