The Murein Types of Listeria grayi, Listeria murrayi and Listeria denitrificans.

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. Copyright © 1983 Gustav Fischer Verlag, Stuttgart/New York. Published by Elsevier GmbH.. All rights reserved.
