Enzymes for RNA Sequence Analysis
The common slime mold Physarum polycephalum secretes a variety of hydrolytic enzymes when grown in submersed cultures. Initiated by the isolation in 1969 of a rather crude RNase, proposed by Braun and Behrens as a useful analytical endonuclease, an extended search was conducted in our laboratory, which revealed that actually two distinct RNases occur, largely outweighed by a yet unknown acid ph...
متن کاملnon-protein enzymes: rna can act as an enzyme
within the past few years, neat scheme has been overturned by the discovery that rna can act as an enzyme. what does the starting finding of rna enzymes imply? thre first implication is that one can no longer assume a protein lies behind every catalytic activity of the cell. it now appears that several of the operations that tailor an ran molecule into its final form are at least in part cataly...

متن کاملRNA enzymes: Putting together a large ribozyme
The crystal structure of a 160-nucleotide domain of a ribozyme provides the first detailed view of an RNA large enough to show side-by-side packing of helices. Several new structural motifs are found: ribose zippers, adenosine platforms and a tetraloop receptor.
متن کاملRibozyme therapy: RNA enzymes to the rescue.
According to the central dogma of biology, ribonucleic acids (RNA)' were thought to play the role of messengers (mRNA) that are mere intermediates between DNA and proteins. Recent advances in understanding the capabilities of RNA have proven this wrong. The catalytic reaction required for making proteins is carried out by RNA [1]. RNA evolved in vitro can bind small molecules with high specific...
