The P-pant moiety serves to tether covalently the growing polypeptide being assembled by NRPSs.
The toluidine blue O moieties served as redox mediators for enzymatic glucose oxidation and as polymeric network to maintain the biosensor activity.
One of the syntheses of grafting polymers is electropolymerization of statistically exposed dithiobenzoate moieties served as a chain transfer agent for the polymerization of styrene on a matrix of an electrodeposited conjugated polymer.
For control experiments, we chose the linear diblock copolymer PS- b-PVP, whose pyridine moieties served as ligands for the AuNPs.
However, identification of an ion series that retains the naphthoquinone structure and differs by 68 Da (designated n2 n9) and an ion that retains only the isoprenoid moiety (designated i1) serves to identify and locate the reduction in the MK tail.
A plausible explanation for this could be the formation of an extended hydrogen-bonding network involving the primary amine hydrogen, protic solvent and carbonyl moiety, once again serving to alter the electronic structure and thus facilitate non-radiative decay, effectively switching off fluorescence.
Its multiple diethylene-triamine-pentaacetic acid (DTPA) moieties chelate and bind tightly to 99mTc, while its multiple mannose moieties serve as ligands for multivalent binding to mannose receptors (CD206) expressed on the surfaces of reticuloendothelial cells resident in lymph nodes.
Together, with a reduced cysteine thiol and amide nitrogen of serine, these moieties serve as ligands for the catalytic metal centre.
In contrast with the FRET approach, stacking interactions between fluorophores are advantageous in the production of efficient excimer emission when pyrene moieties serve as fluorophores [ 37, 40, 174].
Mt-PrsA displays an absolute requirement for inorganic phosphate for enzyme activation and will accept either Mg2+ or Mn2+ as divalent cations, which serve to coordinate the phosphate moieties of ATP during enzyme catalysis.
