Abstract

The amino acid sequences of the mureins of the type strains Listeria grayi ATCC 19120, Listeria murrayi ATCC 25401 and Listeria denitrificans ATCC 14870 were determined. L. grayi and L. murrayi contain the murein variation A1γ (A(2)pm-direct-type) which is also present in the type strain of L. monocytogenes. L. denitrificans has a different murein. It belongs to the variation A4α, exhibiting a γ-D-glutamyl-L-seryl-interpeptide bridge between alanyl-γ-D-glutamyl-lysyl-D-alanine peptide subunits (Lys-Ser-D-Glu-type). The taxonomic implications are discussed.

摘要

对模式菌株灰色李斯特菌（Listeria grayi）ATCC 19120、默里李斯特菌（Listeria murrayi）ATCC 25401 和反硝化李斯特菌（Listeria denitrificans）ATCC 14870 的肽聚糖的氨基酸序列进行了测定。灰色李斯特菌和默里李斯特菌含有肽聚糖变体 A1γ（A(2)pm-直接型），这种变体也存在于单核细胞增生李斯特菌的模式菌株中。反硝化李斯特菌具有不同的肽聚糖。它属于变体 A4α，在丙氨酰-γ-D-谷氨酰-赖氨酰-D-丙氨酸肽亚基之间表现出 γ-D-谷氨酰-L-丝氨酸-内肽桥（Lys-Ser-D-Glu 型）。讨论了分类学意义。
