title: [Synthesis of a fragment of the active center of the streptococcal proteinase (EC 3.4.22.10), VIII (author's transl)].
abstract: The synthesis of the protected tricosapeptide Z-Val-Lys(Z)-Pro-Gly-Glu(OBzl)-Gln-Ser-Phe-Val-Gly-Gln-Ala-Ala-Thr-Gly-His-Cys(MBzl)-Val-Ala-Thr-Ala-Thr-Ala-ONB is described. The tricosapeptide was built up from the decapeptide Z-Val-Lys(Z)-Pro-Gly-Glu(OBzl)-Gln-Ser-Phe-Val-Gly-ONp and the tridecapeptideester Gln-Ala-Ala-Thr-Gly-His-Cys(MBzl)-Val-Ala-Thr-Ala-Thr-Ala-ONB. A further nonadecapeptide with tert-butylmercapto protection of the SH group was also synthetized.
