Descripción general
Bacterial Peptidoglycan is a polymer consisting of sugars and amino acids, a mesh-like rigid layer that forms the cell wall. D-Amino Acids (D-AAs) are metabolically incorporated onto the bacterial cell wall by D,D-transpeptidase and/or L,D-transpeptidase. It was recently discovered that those transpeptidases catalyze the metabolic incorporation of exogenous D-AAs with almost no restriction of the side-chain identity. [1] Modification of a D-AA with molecular fluorophores provides fluorescent d-amino acids that can efficiently label in situ peptidoglycan in diverse bacterial species.[2] Coumarin-labeled D-lysine is a fluorescent derivative of D-lysine that is obtained by a synthetic conjugation of D-lysine to the fluorophore. Coumarin labeled D-lysine has high biocompatibility and suitability for labeling peptidoglycans in live bacteria. Additionally, it can be used in tandem with other stains such as FITC-labeled Alanine (SBR00049) to distinguish between different bacteria. Other compatible products useful for live staining include: Rhodamine B labeled Polymyxin B, FITC Labeled D-Lysine, Alanine or Vancomycin and Dansyl labeled polymyxin B (SBR00036, SBR00050, SBR00049, SBR00028, SBR00029).
Aplicación

- Bacterial cell wall morphology
- Bacterial cell wall formation or remodeling activity
- Bacterial viability/activity
- Identify bacterial activity on surfaces or in substances
- Differentiation between various bacterial strains according to their incorporation profile of different D amino acids and sugars[5]

Fluorescent d-amino acids (FDAAs) enable efficient in situ labeling of peptidoglycan in diverse bacterial species. Conducted by enzymes involved in peptidoglycan biosynthesis, FDAA labeling allows specific probing of cell wall formation/remodeling activity, bacterial growth and cell morphology.

Peptidoglycan (PG), a polymer cross-linked by d-amino acid-containing peptides, is an essential component of the bacterial cell wall. We found that a fluorescent d-alanine analog (FDAA) incorporates chiefly at one of the two poles in Mycobacterium smegmatis but that polar

Tracking a bug's life: Peptidoglycan (PG) of diverse bacteria is labeled by exploiting the tolerance of cells for incorporating different non-natural D-amino acids. These nontoxic D-amino acids preferably label the sites of active PG synthesis, thereby enabling fine spatiotemporal tracking

Production of non-canonical D-amino acids (NCDAAs) in stationary phase promotes remodelling of peptidoglycan (PG), the polymer that comprises the bacterial cell wall. Impairment of NCDAAs production leads to excessive accumulation of PG and hypersensitivity to osmotic shock; however, the mechanistic
