In 1995, Wolfenden reported that without a particular enzyme, a biological transformation he deemed "absolutely essential" in creating the building blocks of DNA and RNA would take 78 million years. "Now we've found a reaction that – again, in the absence of an enzyme – is almost 30 time...
c, Formation of 10 from 6 in the presence of 2 mM NADPH can be observed both with and without PdxG. Compound 6 was obtained from chemical reduction of 5 with NaBH4. Since 10 can be formed in the presence of only NADPH, we conclude NADPH can nonenzymatically reduce the QM to 10, ...

It does this by blocking the effects of an enzyme called lanosterol 14-α-demethylase which is responsible for the formation of ergosterol, an important component of the yeast’s cell wall. This causes toxic substances to build up inside the yeast, reducing its ability to build up and cause...

A tandem syn-selective conjugate addition - Nef reaction was observed when phenylnitromethane and oxygenated derivatives were allowed to react with an enoate derived from D-mannitol at rt in the presence of TBAF or DBU. While nitro-adducts predominate after 4h of reaction, the corresponding ketones...

Structural and Mechanistic Analysis of Drosophila melanogaster Agmatine N-Acetyltransferase, an Enzyme that Catalyzes the Formation of N-Acetylagmatine Purification and properties of L-aspartate-a-decarboxylase, an enzyme that catalyzes the formation of /?-alanine in Escherichia coli - WILLIAMSON, BROWN ...
摘要: We present and evaluate a new and potentially efficient route for enzyme-mediated Diels–Alder reactions, utilizing general acid–base catalysis. The viability of employing the active site of ketosteroid isomerase is demonstrated.关键词:
