DNA-templated polymerization of side-chain-functionalized peptide nucleic acid aldehydes.
The DNA-templated polymerization of synthetic building blocks provides a potential route to the laboratory evolution of sequence-defined polymers with structures and properties not necessarily limited to those of natural biopolymers. We previously reported the efficient and sequence-specific DNA-templated polymerization of peptide nucleic acid (PNA) aldehydes. Here, we report the enzyme-free, D...
متن کاملEfficient and sequence-specific DNA-templated polymerization of peptide nucleic acid aldehydes.
On the basis of the distance-dependence of DNA-templated reductive amination reactions and of recent findings of D. Lynn and co-workers, we developed DNA-templated polymerizations of synthetic peptide nucleic acid (PNA) aldehydes. The coupling reactions proceed in a highly efficient and sequence-specific manner, even in the presence of mixtures of PNA aldehydes of different sequence. Synthetic ...
متن کاملComposition of the Aldehydes of Clostridium Butyricum Plasmalogens. Cyclopropane Aldehydes.
Recent advances in gas-liquid chromatography have permitted the separation and identification of aldehydes derived from plasmalogens, and a number of analyses of aldehydes from animal plasmalogens have been reported (l-3). Bacterial plasmalogens, on the other hand, have only recently been discovered, and no analyses of their fatty aldehydes are available (4-6). Such analyses would be of particu...
متن کاملInteraction of amines with ketone aldehydes and unsaturated aldehydes.
The optical changes occurring during the interaction of amines with ketone aldehydes or unsaturated aldehydes are accompanied by strong electron spin resonance signals, and can thus be explained as due to the transfer of one whole electron in the ground state.
متن کاملPolymerization of propylene in a minireactor: Effect of polymerization conditions on particle morphology
Gas phase polymerization of propylene was carried out in a semi-batch minireactor using a commercially supported Ziegler–Natta (ZN) catalyst. The influence of variables including monomer partial pressure, external electron donor, reaction temperature and time on the particle morphology and size distribution was investigated. Generally, more uniform fragmentation and particle densities were obta...
