The nucleophilic lysine residue is commonly targeted site in protein bioconjugation, typically through amine-reactive N-hydroxysuccinimidyl (NHS) esters. [3] To obtain optimal number of deprotonated lysine residues, the pH of the aqueous solution must be below the pKa of the lysine ammonium group, which is around 10.5, so the typical pH of the reaction is about 8 and 9.

The D mesons were discovered in 1976 by the Mark I detector at the Stanford Linear Accelerator Center. [3]Since the D mesons are the lightest mesons containing a single charm quark (or antiquark), they must change the charm (anti)quark into an (anti)quark of another type to decay.
In fact, such bands are observed, but are weak, having intensities orders of magnitude weaker than "allowed" bands. The extinction coefficients for d-d bands are in the range 5–200. [3] The allowedness of d-d bands arises because the centre of symmetry for these chromophores is disrupted for various reasons. The Jahn–Teller effect is one ...
EF-G in pathogenic bacteria can be inhibited by antibiotics that prevent EF-G from binding to the ribosome, [19] carrying out translocation [20] or dissociating from the ribosome. [ 21 ] For example, the antibiotic thiostrepton prevents EF-G from binding stably to the ribosome, [ 19 ] while the antibiotics dityromycin and GE82832 inhibit the ...
