| Comments |
Concern about preserving all cross-links at all times is probably overdone. It seems likely to JT Park that
the cell can manage with less than a normal number of cross-links in its sacculus. There are about 3.5×10^6 muropeptides in a sacculus (Wientjes et al 1991 PMID 1938964) and only about 700,000 cross-links so that considerably less than half
of the muropeptides are involved in cross-links. Certainly the cell manages very well without its sacculus
being completely cross-linked. |
