Lysine properties

The choice of a suitable immobilization method for a given enzyme and appHcation is based on a number of considerations including previous experience, new experiments, enzyme cost and productivity, process demands, chemical and physical stabiHty of the support, approval and safety issues regarding support, and chemicals used. Enzyme characteristics that greatly influence the approach include intra- or extraceUular location size surface properties, eg, charge/pl, lysine content, polarity, and carbohydrate and active site, eg, amino acids or cofactors. The size, charge, and polarity of the substrate should also be considered. [Pg.291]

Besides all the sensory and texturizing properties, GA has interesting antioxidant properties such as an efficient capacity for deactivation of excited electronic states and moderated radical scavenging capacity. There is increasing experimental evidence that associate the antioxidant function with its protein fraction, mainly by amino acid residues such as histidine, tyrosine and lysine, which are generally considered as antioxidants molecules (Marcuse, 1960,1962 Park et al., 2005). [Pg.18]

Note The amino acid residues of lysine (K) and arginine (R) which may be responsible for the binding of POs to polysaccharides are in bold. According to Demand et al. (2002), the mutual substitution of these amino acids has no influence on the sorption properties of the ATg08770 PO of Arabidopsis with pectins, and the deletion of the fragment results in the loss of this function. [Pg.209]

In contrast to MDA and hydroxynonenai, other aldehyde products of lipid peroxidation are hydrophobic and remain closely associated with LDL to accumulate to mil-limolar concentrations. Aldehydes at these elevated levels react with the protein portion of the LDL molecule, apolipoprotein B (apoB). Accumulated aldehydes bind the free amino groups from lysine residues in addition to other functional groups (-OH, -SH) on the apoB polypeptide. Consequently, the protein takes on a net negative charge and complete structural rearrangement results in the formation of ox-LDL. ox-LDL is no longer recognized by the LDL receptor, and has several pro-inflammatory properties (discussed below). [Pg.103]

POLY(AMINO acids). Both anionic [e.g., poly(L-aspartic acid) and poly(glutamic acid)] and cationic [e.g., poly[L-lysine)] poly(amino acids) have been suggested as potential drug carriers. Poly(L-lysine) is a homopolymer cosisting of repeating units of L-lysine. It exhibits some affinity for cancer cells and possesses antimicrobial and antiviral properties. It also shows... [Pg.573]

More than 36 years ago, the pH-induced cooperative transitions in CD spectra and other physical properties of poly-L-glutamic acid (PGA) and poly-L-lysine (PL) were reported and taken to correspond to a... [Pg.187]
