Covalent enzyme-RNA complex: a tRNA modification that prevents a covalent enzyme interaction also prevents aminoacylation.
Previous work indicates that aminoacyl-tRNA synthetases make a transient covalent adduct with cognate tRNAs, through Michael addition of an enzyme nucleophile to the carbon-6 position of uridine 8. We report the selective reduction of the 5,6 double bond of 4-thiouridine at position 8 in Escherichia coli tyrosine tRNA, so as to prevent formation of the presumed covalent enzyme-nucleic acid addu...
متن کاملIncrease of enzyme activity through specific covalent modification with fragments.
Modulation of enzyme activity is a powerful means of probing cellular function and can be exploited for diverse applications. Here, we explore a method of enzyme activation where covalent tethering of a small molecule to an enzyme can increase catalytic activity (kcat/KM) up to 35-fold. Using a bacterial glycoside hydrolase, BtGH84, we demonstrate how small molecule "fragments", identified as a...
متن کاملOperating regimes of covalent modification cycles at high enzyme concentrations.
The Goldbeter-Koshland model has been a paradigm for ultrasensitivity in biological networks for more than 30 years. Despite its simplicity the validity of this model is restricted to conditions when the substrate is in excess over the converter enzymes - a condition that is easy to satisfy in vitro, but which is rarely satisfied in vivo. Here, we analyze the Goldbeter-Koshland model by means o...
متن کاملRNA modification enzyme TruB is a tRNA chaperone.
Cellular RNAs are chemically modified by many RNA modification enzymes; however, often the functions of modifications remain unclear, such as for pseudouridine formation in the tRNA TΨC arm by the bacterial tRNA pseudouridine synthase TruB. Here we test the hypothesis that RNA modification enzymes also act as RNA chaperones. Using TruB as a model, we demonstrate that TruB folds tRNA independent...
متن کاملRNA-assisted catalysis in a protein enzyme: The 2'-hydroxyl of tRNA(Thr) A76 promotes aminoacylation by threonyl-tRNA synthetase.
Aminoacyl-tRNA synthetases (aaRSs) join amino acids to 1 of 2 terminal hydroxyl groups of their cognate tRNAs, thereby contributing to the overall fidelity of protein synthesis. In class II histidyl-tRNA synthetase (HisRS) the nonbridging S(p)-oxygen of the adenylate is a potential general base for aminoacyl transfer. To test for conservation of this mechanism in other aaRSs and the role of ter...
