Article name: Peptidoglycan (link)

1. Citations

Generally speaking, most of the presented facts are supported by appropriate and reliable references. For example, the comment about MreB proteins is supported by one academic journal and two papers that place MreB as the centerpiece of discussion. Very few facts are supported by less reliable sources as in the case of the comment made on NAM and NAG sugars, which was based on a blog post. The article shows little signs of plagiarism and closed paraphrasing. While some references can be looked up in literature databases, not all of them are assigned working hyperlinks.

2. Content

The article discusses the structure and biosynthesis of peptidoglycan in great depths while placing a lighter emphasis on inhibition and pseudopeptidoglycan.

The article excels at providing a good overview of Peptidoglycan without expressing any biases towards a particular position. Viewpoints presented were generally neutral and equally represented. The subjects of antibiotic (i.e. Penicillin) and antibiotic resistance (i.e. transpeptidase mutations) are brought up very briefly near the end of Inhibition. A potential revision could extend the discussion of peptidoglycan structure to the role of peptidoglycan in bacterial virulence and its susceptibility to antibiotic treatments.

3. Revisions

One Wikipedia contributor pointed out that gram-staining was overlooked in one of the earlier versions of the article. There was also a comment about whether or not it was necessary to supplement the discussion of peptidoglycan structure and sugar cross-linking with diagrams. Both of these issues were adequately addressed shortly after being brought to attention.
