The Covalently Linked Sacculus: the Nona-Muropeptide Model

  • Arthur L. Koch

Abstract

A bacterial cell wears a stress-bearing suit of armor: the sacculus or exoskeleton. In E. coli it is composed of hundreds of thousands of disaccharide penta-muropeptides polymerized together. There are even more in the Grampositive B. subtilis. Of course, the penta-muropeptide units are held together by strong covalent bonds, as shown in Figure 6.1, and these individual units are bound together with additional covalent bonds to make the sacculus strong.
