Architecture-Controlled Ring-Opening Polymerization for Dynamic Covalent Poly(disulfide)s.

Summary of "Architecture-Controlled Ring-Opening Polymerization for Dynamic Covalent Poly(disulfide)s."

A strategy is reported for controlling the architecture of poly(disulfide)s by ring-opening polymerization. Aryl thiol initiators shift the ring-chain equilibrium to yield cyclic polymers while alkyl thiols favor linear ones. Control over polymerization enables the synthesis of high polymers (630 kDa) and catalytic depolymerization of polymers to recycle monomers. This work provides a new avenue to create dynamic covalent polymers with controlled geometry and length, allowing better characterization of structure-property relationships to expand their materials potential.

Medical and Biotech [MESH] Definitions

A poly(ADP-ribose) polymerase that contains two ZINC FINGERS in its N-terminal DNA-binding region. It modifies NUCLEAR PROTEINS involved in chromatin architecture and BASE EXCISION REPAIR with POLY ADENOSINE DIPHOSPHATE RIBOSE.

A protein motif 22 to 26 amino acids in length that binds POLY(ADP RIBOSE) polymers through non-covalent interactions. It is characterized by basic and hydrophobic residues that frequently include ALANINE; VALINE; ISOLEUCINE; or LEUCINE and flank LYSINE and ARGININE amino acids.

Architecture, exterior and interior design, and construction of facilities other than hospitals, e.g., dental schools, medical schools, ambulatory care clinics, and specified units of health care facilities. The concept also includes architecture, design, and construction of specialized contained, controlled, or closed research environments including those of space labs and stations.

A poly(A) binding protein that is involved in promoting the extension of the poly A tails of MRNA. The protein requires a minimum of ten ADENOSINE nucleotides in order for binding to mRNA. Once bound it works in conjunction with CLEAVAGE AND POLYADENYLATION SPECIFICITY FACTOR to stimulate the rate of poly A synthesis by POLY A POLYMERASE. Once poly-A tails reach around 250 nucleotides in length poly(A) binding protein II no longer stimulates POLYADENYLATION. Mutations within a GCG repeat region in the gene for poly(A) binding protein II have been shown to cause the disease MUSCULAR DYSTROPHY, OCULOPHARYNGEAL.

The art and science of designing buildings and structures. More generally, it is the design of the total built environment, including town planning, urban design, and landscape architecture.
