Hydrierung vonStenothricin durch Partialhydrolyse erhaltene Fragmente zeigen, daß das schon früher identifizierte Tripeptid D-aThr-L-Ser-L-Dprüber DH-Abu an das Tetrapeptid L-Val-D-Ser-L-Lys-Sar gebunden ist. Die Carboxygruppe von Sar ist außerdem mit der Hydroxygruppe von D-aThr verestert. Die durch β-Ketoacylreste N-acylierte D-Cysteinsäure bildet den N-Terminus und ist über die Aminogruppe von D-aThr
