Descrição geral
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. Modification of a D-AA with molecular fluorophores provides fluorescent D-amino acids that can efficiently label in situ peptidoglycan in diverse bacterial species. Rhodamine-Labeled D-lysine (TDL) is a fluorescent derivative of D-lysine that is obtained by a synthetic conjugation of D-lysine to the fluorophore. Rhodamine 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 D-Alanine (SBR00049) to distinguish between different bacteria. Other compatible products useful for live staining include: Rhodamine B Labeled Polymyxin B, FITC Labeled D-Lysine, FITC Labeled Vancomycin and Dansyl Labeled Polymyxin B (SBR00036, SBR00050, SBR00028, SBR00029 and SBR00047).
Aplicação
Fluorescent labeled D-AAs (FDAAs) can be used for many applications including:
- 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

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.

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
