✦ Synopsis

The pentapeptide was electrophoretically and chromatographically homogeneous and on total hydrolysis gave the amino acids Phe. Glu, Gly. Leu, and Tyr in the proportions 0.98 : 1.13 : 1.00 : 1.07 : 0.89 (D. Georgopoulos). In the plastein reactionr31 with pepsin, a 25-mg sample gave 14 mg (60%) of water-insoluble polypeptide mixture. Paper electrophoresis at p H 6.5 separated the blocked intermediate peptides into the four expected constituents (2carboxy-3-nitrobenzoyl derivatives of Phe, Glu-Phe, Gly-Glu-Phe, and Leu-Gly-Glu-Phe), which appeared with approximately equal intensity on development with the tertbutyl hypochlorite-tolidine reagent 141.
