In the kinetically controlled approach of peptide synthesis mediated by α-chymotrypsin, the broadening of the protease’s substrate tolerance is achieved by switching the acyl donor from the conventional Me ester to the carbamoylmethyl ester. Thus, as a typical example, the extremely low coupling efficiency obtained by employing the Me ester of an inherently poor amino acid substrate, Ala, is significantly improved by the use of this particular ester. Its ameliorating effect is observed also in the couplings of other amino acid residues such as Gly and Ser as carboxy components.

The enzyme-catalyzed hydrolysis of peptide and amide substrates results in the generation of ionic species, which in turn lead to a change in the elec. conductivity of the reaction medium. By recording this phys. property, it is possible to study the kinetics of the hydrolytic reactions. The principle of the conductometric method is given, and its application to the assay of proteolytic enzymes is illustrated by a number of reactions catalyzed by chymotrypsin Aα (EC 3.4.21.1) and trypsin (EC 3.4.21.4). The measured signal is related to product concentration by the molar conductivity coefficient (Λb). The measurement of Λb is described; it varies with the exptl. conditions, particularly when different buffer systems are used. The kinetic results (i.e., values of kcat and Km) for the chymotrypsin Aα and trypsin-catalyzed hydrolysis of a number of specific peptide and amide substrates are given. The results agree closely with previously published values obtained by a number of other assay techniques.

Author is Shigemitsu, Kaori; Tsujishita, Yosuke; Miyake, Hiroshi; Hidayat, Sujuti; Tanaka, Noriaki; Hara, Kenta; Yonezawa, Kazuyoshi.

The addition of leucine induced activation of p70S6k in amino acid-depleted H4IIE cells. Whereas the activation of p70S6k by leucine was transient, the complete amino acid stimulated p70S6k more persistently. The effect of leucine on p70S6k was sensitive to rapamycin, but less sensitive to wortmannin. Using various amino acids and derivatives of leucine, we found that the chirality, the structure of the four branched hydrocarbons, and the primary amine are required for the ability of leucine to stimulate p70S6k, indicating that the structural requirement of leucine to induce p70S6k activation is very strict and precise. In addition, some leucine derivatives exhibited the ability to stimulate p70S6k and the other derivatives acted as inhibitors against the leucine-induced activation of p70S6k.
