从新月柄杆菌的胞壁素囊的胞壁素酶消化的高压液相色谱显示，在细胞中的D-丙氨酸羧肽酶活性的情况下，反映了非常高的含量的五肽的胞壁素。大约一半的五肽侧链显示含有甘氨酸，其取代D-丙氨酸作为末端氨基酸。
High-pressure liquid chromatography of a muramidase digest of murein sacculi from Caulobacter crescentus showed that the absence of D-alanine carboxypeptidase activity in the cells was reflected by a very high content of pentapeptide in the murein. Approximately half of the pentapeptide side chains were shown to contain glycine, which replaced D-alanine as the terminal amino acid.
