A note on the specificity of the enzymatic cleavage of thioethers.
The specificity of the cleavage of thioether compounds related to cysteine by an enzyme from liver tissue of rats was described in an earlier report (I), and experiments as to the availability of thioether derivatives of cysteine and homocysteine for growth have been reported from this laboratory (2). This report is concerned with a brief description of studies of the cleavage of t.he thioether...
متن کاملEnzymatic cleavage of S-adenosylmethionine.
S-adenosylmethionine, known for some time to be the biological methyl donor in mammalian enzymatic transmethylation reactions (1,2), has more recently been implicated in other transalkylation reactions in bacteria and yeast (3-6). The enzyme system catalyzing the condensation of ATP and methionine to form AMe’ has been found in a variety of tissues and organisms, and has been purified from two ...
متن کاملEnzymatic Cleavage of RNA by RNA
The transfer of genetic information from nucleic acid to protein inside cells can be re, presented as shown in Fig. 1. This simple scheme reflects accurately the fact that the information contained in the linear arrangement of the nucleotides in DNA is copied accurately into the linear arrangement of nucleotides in RNA which, in turn, is translated by machinery inside the cell into proteins, th...
متن کاملSite specific enzymatic cleavage of RNA
The hybridization of a DNA oligonucleotide a specific tetramer or longer) will direct a cleavage by RNase H (EC 3.1.4.34) to a specific site in RNA. The resulting fragments can then be labeled at their 5' or 3' ends, purified, and sequenced directly. This procedure is demonstrated with two RNA molecules of known sequence: 5.8S rRNA from yeast (158 nucleotides) and satellite tobacco necrosis vir...
