The synthetic … Ribozymes (ribonucleic acid enzymes) are RNA molecules that have the ability to catalyze specific biochemical reactions, including RNA splicing in gene expression, similar to the action of protein enzymes. The 1982 discovery of ribozymes demonstrated that RNA can be both genetic material … See more Before the discovery of ribozymes, enzymes—which are defined as catalytic proteins —were the only known biological catalysts. In 1967, Carl Woese, Francis Crick, and Leslie Orgel were the first to suggest that RNA … See more Although ribozymes are quite rare in most cells, their roles are sometimes essential to life. For example, the functional part of the ribosome, the biological machine that translates RNA into proteins, is fundamentally a ribozyme, composed of RNA tertiary structural motifs See more Since the discovery of ribozymes that exist in living organisms, there has been interest in the study of new synthetic ribozymes made in … See more Well-validated naturally occurring ribozyme classes: • GIR1 branching ribozyme • glmS ribozyme • Group I self-splicing intron See more Despite having only four choices for each monomer unit (nucleotides), compared to 20 amino acid side chains found in proteins, ribozymes have diverse structures and mechanisms. In many cases they are able to mimic the mechanism used … See more RNA can also act as a hereditary molecule, which encouraged Walter Gilbert to propose that in the distant past, the cell used RNA as both … See more Ribozymes have been proposed and developed for the treatment of disease through gene therapy.
