Tryptophan rna-binding attenuation protein
WebMay 25, 2016 · The endoplasmic reticulum (ER) is involved in calcium homeostasis, protein folding and lipid biosynthesis. Perturbations in its normal functions lead to a condition called endoplasmic reticulum stress (ERS). This can be triggered by many physiopathological conditions such as alcoholic steatohepatitis, insulin resistance or ischemia-reperfusion … WebCentral to this combinatorial mechanism are the homo-oligomeric proteins TRAP (trp RNA-binding attenuation protein) and anti-TRAP (AT).

WebIn Bacillus subtilis, tryptophan biosynthesis is regulated by a mechanism called attenuation. The new crystal structure of the ‘trp RNA binding attenuation protein’, TRAP, in complex … WebThis nascent RNA chain adopts an alternative secondary structure that does not interact appropriately with the RNA polymerase. In order for gene expression to proceed, regulatory proteins must bind to the RNA chain and remove the attenuation, which is costly for the cell. In prokaryotes there are two mechanisms of transcription attenuation.
