peptidoglycan Biochem.|pɛpˌtaɪdəʊˈglaɪkæn|
[f. peptide + -o + glyco- + -an.]
= murein; also, the mucopolysaccharide which forms the strands of this.
1966Biochem. V. 82/1 The biosynthesis of peptidoglycan (mucopeptide) in cell-free extracts of Staphylococcus aureus..has been described by Chatterjee and Park. Ibid. 3091 The mechanical strength of the peptidoglycan polymer which forms the rigid network of all bacterial cell walls depends on a high degree of cross-linking between peptide and polysaccharide chains. 1968A. White et al. Princ. Biochem. (ed. 4) xli. 910 Murein synthesis..may be regarded as proceeding in three stages: synthesis of the precursor units, synthesis of the linear peptidoglycan strands, and cross-linking. 1969New Scientist 10 July 64/1 A major component of the cortex layer [of a bacterial spore] is the polymer murein (or peptidoglycan). 1975Nature 10 Apr. 482/2 The walls of all penicillin-sensitive organisms contain a structural component called peptidoglycan, which consists of glycan chains of alternating residues of N-acetylglucosamine and its 3-O-d-lactyl ether..and d-amino acids. |
