Two endopeptidases have been characterized in Bacillus sphaericus 9602: a gamma-D-glutamyl-(L) meso-diaminopimelate endopeptidase (endopeptidase I) and a gamma-D-glutamyl-L-diaminoacid endopeptidase (endopeptidase II). They are active on the peptide moieties of some bacterial peptidoglycans. Their specificities have been studied on peptides or monomeric glycopeptides derived from peptidoglycans. Their study was attempted on dimeric and polymeric fragments of a E. coli radioactive peptidoglycan. Those compounds are specifically labelled on the meso-diaminopimelate residues and are listed below.
在球形芽孢杆菌9602中已鉴定出两种内肽酶：一种γ-D-谷氨酰-（L）-内消旋二氨基庚二酸内肽酶（内肽酶I）和一种γ-D-谷氨酰-L-二氨基酸内肽酶（内肽酶II）。它们对某些细菌肽聚糖的肽部分具有活性。已对源自肽聚糖的肽或单体糖肽研究了它们的特异性。还尝试对大肠杆菌放射性肽聚糖的二聚体和多聚体片段进行研究。这些化合物在中消旋二氨基庚二酸残基上被特异性标记，如下所示。
