The Diels-Alderase ribozyme, an in vitro-evolved ribonucleic acid enzyme, accelerates the formation of carbon-carbon bonds between an anthracene diene and a maleimide dienophile in a [4 + 2] cycloaddition, a reaction with broad application in organic chemistry. Here, the Diels-Alderase ribozyme is examined via molecular dynamics (MD) simulations in both(More)
The restriction endonuclease EcoRV binds two magnesium ions. One of these ions, Mg(A)(2+), binds to the phosphate group where the cleavage occurs and is required for catalysis, but the role of the other ion, Mg(B)(2+) is debated. Here, multiple independent molecular dynamics simulations suggest that Mg(B)(2+) is crucial for achieving a tightly bound(More)
The Diels-Alderase ribozyme is an in vitro-evolved ribonucleic acid enzyme that catalyzes a [4 + 2] cycloaddition reaction between an anthracene diene and a maleimide dienophile. The ribozyme can in principle be used to selectively synthesize only one product enantiomer, depending on which of the two entrances to the catalytic pocket, "front" or "back", the(More)
