D-Ala-D-Ala
D-Ala-D-Ala is a bacterial endogenous metabolite. D-Ala-D-Ala constitutes the terminus of the peptide part of the peptidoglycan monomer unit and is involved in the transpeptidation reaction as the substrate. D-Ala-D-Ala is catalyzed by D-Alanine-D-Alanine ligase [1] [2] [3]. Uses: Scientific research. Group: Peptides. CAS No. 923-16-0. Pack Sizes: 100 mg; 250 mg; 1 g; 5 g. Product ID: HY-W015450.
D-Ala-D-Ala dipeptidase
A Zn2+-dependent enzyme. The enzyme protects Enterococcus faecium from the antibiotic vancomycin, which can bind to the -D-Ala-D-Ala sequence at the C-terminus of the peptidoglycan pentapeptide (see diagram). This enzyme reduces the availability of the free dipeptide D-Ala-D-Ala, which is the precursor for this pentapeptide sequence, allowing D-Ala-(R)-lactate (for which vancomycin has much less affinity)to be added to the cell wall instead. The enzyme is stereospecific, as L-Ala-L-Ala, D-Ala-L-Ala and L-Ala-D-Ala are not substrates. Belongs in peptidase family M15. Group: Enzymes. Synonyms: D-alanyl-D-alanine dipeptidase; vanX D-Ala-D-Ala dipeptidase; VanX. Enzyme Commission Number: EC 3.4.13.22. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder.
