or branched polymers has been dealt with in the past by several authors, frequently in the context of chain scission . Chain scission may create reactive chain ends that undergo recombination to form longer ...
Mimicking giant cylindrical micelles in solution, self-assembled linear polymers are studied by Langevin dynamics in shear flow. The kinetics of chain scission (with rate ks per bond) and chain end ...
, which show that arginine residues mediate a tight binding (Hileman et al., 1998). This can be explained by the presence of a flexible side chain ending in a guanidinium cation highly suitable to form ...
granule is composed of amylopectin, a highly branched polymer consisting of α-1,4-linked linear glucan chains with α-1,6-linked branches. The structure of amylopectin facilitates the formation of double ...
of inflicting various types of DNA damage. Of the DNA lesions created, probably the most dangerous is the double-strand break, as it generates loose ends , which have great potential to inappropriately recombine ...
mutant fGSCs showed abscission defects: linear chains (~20% in alix3 and ~10% in alix1), branched chains (~40% in alix3 and ~30% in alix1) or polyploidy (~2% in alix3 and ~30% in alix1) (Figs. 3F-H and S7C ...
to a xyloglucan chain , thus creating a chimaeric polymer with MLG at one end and xyloglucan at the other. This may contribute to strengthening the Equisetum stem in mature plants, helping it to resist wind damage ...
structural role these matrix polymers play in the cell walls of higher plants. Xyloglucans are major components of the primary wall of all dicots and some monocots (Carpita and McCann, 2000), where they bridge ...
be efficiently taken up by mammalian cells (17,18). Complexing anionic DNA with cationic polymers to form nanoparticles is an advanced strategy for inducing cellular uptake of DNA (19). Nucleosomes themselves ...
, understanding the remodelling of homogalacturonan (HG), the most abundant pectic polymer , by specific enzymes is a current challenge in addressing its fundamental role. HG, a polymer that can be methylesterified ...
