Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalysthttp://goldbook.iupac.org/C00876.html, which is not consumed in the catalyzed reaction and can continue to act repeatedly.
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.
Enzymes are macromolecular biological catalysts.
Guanine (or G, Gua) is one of the four main nucleobases found in the nucleic acids DNA and RNA, the others being adenine, cytosine, and thymine (uracil in RNA).
In vitro (meaning: in the glass) studies are performed with microorganisms, cells, or biological molecules outside their normal biological context.
This page lists enzymes by their classification in the International Union of Biochemistry and Molecular Biology's Enzyme Commission numbering system.
Ribosomal ribonucleic acid (rRNA) is the RNA component of the ribosome, and is essential for protein synthesis in all living organisms.
S-Adenosyl methionineSAM-e, SAMe, SAM, S-Adenosyl-L-methionine, AdoMet, ademetionine is a common cosubstrate involved in methyl group transfers, transsulfuration, and aminopropylation.
S-Adenosyl-L-homocysteine (SAH) is an amino acid derivative used in several metabolic pathways in most organisms.
