Trp, Leu, Met), and it was selected for making the Tyr-Gly, Phe-Leu, and Phe-Met peptide bonds. Papain was selected for Gly-Gly and Gly-Phe peptide bonds. Bromelain is very similar to papain as far as its specificity. All these proteases are serine or cysteine type, and the peptide bond formation can be done under kinetically controlled conditions. Thermolysin is an asparyl protease, and it was selected mainly for Phe-Leu and Gly-Phe bonds. MeCN, EtOAc, and methyl caproate were used as solvents with a controlled amount of buffer or at fixed water amount. 

In 1956, my brief from Archer Martin was to invent a more sensitive detector for gas chromatography. When a low voltage was applied to an ionization detector so that only thermal electrons are collected, a 1 mg sample of an allegedly pure sample of methyl caproate gave a never ceasing range of off scale peaks. I shall never forget the of amazement on Tony James face. There were two problems with the detector, it was too sensitive and it was erratic. When I tried a mixture made up in the solvent CCLt the current fell to zero and there remained.
