A polymer is a macromolecule composed of smaller repeating subunits called monomers/oligomers. In the SLA 3D printing process, the resin (ink) is composed of photosensitive monomers/oligomers capable of undergoing photopolymerization on exposure to light to form polymers. Therefore, the photopolymers ar...
Real-time AFM has allowed us to visualize the cleavage of in-chain disulfide bonds in a single mucin molecule, and subsequent removal from the substrate of mucin subunits between disulfide sites. In contrast, mucins that were covalently bound via amine groups to a self-assembled succinimide ...
Each IFT train is a polymer of two large complexes IFT-A and IFT-B with molecular weight of ~0.8 MDa and 1 MDa, respectively5. The IFT-B complex comprises of a 10-subunit core subcomplex IFT-B1 and a 6-subunit peripheral subcomplex IFT-B2, mediating the anterograde trafficking (toward ...
The paper provides a detailed overview of heterogeneous chemical reactions leading to the electrode surface modification and further reactivity of various functionalized surfaces. Notably, the present paper is different from other typical reviews and books about chemically modified electrodes—it is not aime...
A growing body of work suggests that the material properties of biomolecular condensates ensuing from liquid–liquid phase separation change with time. How this aging process is controlled and whether the condensates with distinct material properties can
("Theoretical prediction of solubility" section).Swellingof paint, a tangible phenomenon for a conservator, has two distinct aspects: equilibrium swelling and swelling kinetics.Equilibrium swellingis partly governed by thermodynamics, but needs additional parameters concerning polymer properties.Swelling ...
Urease activity is widespread among theprokaryotes. Ureases from urea hydrolyzing bacteria are generally made up of two or three subunits (ureA, ureB, and ureC) and involve many accessory proteins (e.g., ureD, ureE, ureF, ureG, ureH, and ureI) for their activation[26],[27]. The majo...
Xayarath B, Yother J: Mutations blocking side chain assembly, polymerization, or transport of a Wzy-dependent Streptococcus pneumoniae capsule are lethal in the absence of suppressor mutations and can affect polymer transfer to the cell wall. J Bacteriol. 2007, 189 (9): 3369-3381. 10.1128/JB...
The FtsZ protein is a central component of the bacterial cell division machinery. It polymerizes at mid-cell and recruits more than 30 proteins to assemble into a macromolecular complex to direct cell wall constriction. FtsZ polymers exhibit treadmilling dynamics, driving the processive movement of ...
The still closest match was to round N and A down to 1 per repeat unit, T up to 2, and P up to 1. The order of residues was set by matching dipeptide- and three-peptide frequencies to the original MacNup98A FG domain. We refer to the now perfectly repeated GGLFGGNTQPAT sequence...
