Summary of muropeptide composition of <i>C. jejuni</i> wild-type 81-176, Δ<i>pgp1</i> mutant, Δ<i>pgp1</i> complement (Δ<i>pgp1</i>c), and <i>pgp1</i> overexpression (81-176+<i>pgp1</i>) strains, and the resultant Δ<i>pgp1</i> PG profiles of Pgp1 activity assays consisting of Δ<i>pgp1</i> PG incubated without enzyme, with Pgp1 in the presence of ZnCl₂, and with Pgp1 without ZnCl₂ but with EDTA.

1<p>Numbers represent the percent area of each muropeptide from <a href="http://www.plospathogens.org/article/info:doi/10.1371/journal.ppat.1002602#ppat.1002602.s006" target="_blank">Table S4</a> calculated to give a total of 100%. Values indicated with an asterisk (*) represent an equal to or greater than 20% difference in comparison to wild-type 81-176 or Δ<i>pgp1</i> PG to which no enzyme was added; bolded asterisked values (<b>*</b>) indicate a greater than 30% change.</p>2<p>Values for the percentage of O-acetylated species do not represent the true level of PG O-acetylation in these strains, as most O-acetyl groups are lost in the standard alkaline muropeptide reduction procedure used in this study.
