Biological information is stored by DNA and manifested by proteins. RNA serves as the
conduit: 1 The flow of information through RNA is essential for known life. By catalyzing the …

The various mechanisms by which RNA is hydrolyzed are currently under intense
investigation. The first step in the hydrolysis pathway is a cleavage–transesterification in …

A series of catecholato phosphonium ions, including the first stable bis (catecholato)-
substituted derivatives, are isolated and fully characterized. The cations rank among the …

Micelles are prevalent in naturally occurring and biological catalytic reactions. However, it is
only in recent decades that scientists have developed kinetic models clarifying how micelle …

hydrolysis of the P-O5** bond in RNA. This reaction occurs in two steps …

The term Lewis acid catalysts generally refers to metal salts like aluminium chloride, titanium
chloride and zinc chloride. Their application in asymmetric catalysis can be achieved by the …

Bovine pancreatic ribonuclease A (RNase A) catalyzes the cleavage of the P-O5′ bond in
RNA. Although this enzyme has been the object of much seminal work in biological …

Phosphonium salts as a novel metal-free Lewis acid catalyst can be considered as
organocatalysts. The introduction of a five-membered dioxaphosphacycle to the …

The guanidinium functional group is commonly used by proteins and enzymes to recognize
and bind anions using ion pairing and hydrogen bonding. The specific patterns of hydrogen …
