詳細

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.
Fluorescein Labeled D-Alanine is a fluorescent derivative of D-alanine that is obtained by a synthetic conjugation of 3-amino-D-alanine to a fluorophore. Fluorescein Labeled D-Alanine has high biocompatibility and suitability for labeling peptidoglycans in live bacteria

アプリケーション

Fluorescent labeled D-AAs 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

アナリシスノート

  • Fluorescent microscopy application: Fluorescein Labeled D-Alanine has excitation/emission wavelength range at 495 nm/515 nm.
  • The recommended working concentration in fluorescent microscopy imaging application is between 250 μM-500 μM in DMSO.
  • Aliquots of the DMSO solution can be stored at -20°C, protected from light for at least one month.

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. Their broad application

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
