The research demonstrates for the first time that a precursor to transfer RNA -- the genetic material that is responsible for synthesizing proteins -- could have acted as the catalyst for reactions that link transfer RNA (tRNA) to amino acids in a pre-biological era.

Background Knowledge: Enzyme: Enzymes are proteins which act as a Biological Catalyst. A catalyst alters the rate of reaction without itself changes. Research indicates that enzymes combine with the molecules they act upon (called Substrates) to form an enzyme-substrate complex.

Recently, hitherto unrecognized types of biological reactions have been uncovered that do not involve redox shuffles, and might involve the reduced form of the flavin as a catalyst. The present work addresses properties of reduced flavin relevant in this context.

Normally chemical reactions do not proceed spontaneously, but require the help of a catalyst. A catalyst accelerates a chemical reaction without itself being changed. For example, the reaction of hydrogen with oxygen to produce water requires the addition of the metal platinum. ... Biological catalysts are called enzymes.
