Structure-dependent differences in DNA binding are shown by gel electrophoretic retardation of DNA and thermal transition analyses. Two PAAs, NG28 and NG30, stand out as having high affinity DNA binding characteristics, similar to the model homopolypeptide, poly- L-lysine. In addition, differences...
Lysine (Lys) residues in proteins undergo a wide range of reversible post-translational modifications (PTMs), which can regulate enzyme activities, chromatin structure, protein-protein interactions, protein stability, and cellular localization. Here we discuss the "writers," "erasers," and "readers"...
a, The chemical structure of free SBD-NHS probe and labelled SBD structure on the N-terminus or lysine residuals of ELP. b, The chemical structure of SBD-methyl ester. SBD-methyl ester resembled the chemical structure of labelled SBD on proteins, hence was used for photophysical property measu...
Coded amino acid L-lysine is utilized for the design of a chemical nuclease model wherein the α-amino carboxylate unit of the amino acid is used for the formation of the copper complex acting as the metal cleaving centre, and the ω-amino function of the molecule is exploited to carry th...
The chemical structure of tryptophanase from Escherichia coli. I. Isolation and structure of a pyridoxyl decapeptide from borohydride-reduced holotryptopha... Following reduction with NaBH, carboxymethylation, and chymotryptic digestion, a decapeptide containing the -pyridoxyllysine residue was isolated...

Polymeric biomaterials have extensively been used in medicinal applications. However, factors that determine their biocompatibility are still not very clear. This article reviews various effects of the chemical structure and the surface properties of polymeric biomaterials on their biocompatibility, including ...
Physico-chemical structure of foods and CHO digestion 来自 Semantic Scholar 喜欢 0 阅读量: 18 作者:M Champ,F Guillon,JL Barry 摘要: Carbohydrates are the main energy source of our diet. A large part of these carbohydrates are absorbed as glucose in the small intestine whereas 'indigestible' ...
Posttranslational modifications alter the structure and function of proteins. Now, genetic code expansion enables encoding of ε-N-succinyllysine and ε-N-glutaryllysine residues to decipher the effects of these modifications on enzymatic activity, protein–protein interactions and protein–DNA interactions...
enables the preparation of modified proteins that are not easily fabricated by other methods. In contrast to recombinant approaches, chemical synthesis can be used to prepare protein analogues such asD-proteins, which are useful in protein structure determination and the discovery of novel therapeutics....
