D-ALA-D-ALA-BASED DIPEPTIDES AS TOOLS FOR IMAGING PEPTIDOGLYCAN BIOSYNTHESIS
-
Paragraph 0186-0190, (2016/08/29)
Disclosed herein are compositions for assessing peptidoglycan biosynthesis in bacteria using modified dipeptides containing a bioorthogonal tag and applying novel post-labeling methods to label the bioorthogonal tag. The resultant, labeled peptidoglycan structures are amenable for identifying bacteria by microscopic visualization.
N6-(2-(R)-propargylglycyl)lysine as a clickable pyrrolysine mimic
Li, Xin,Fekner, Tomasz,Chan, Michael K.

Clickable copycat! Readily available dipeptide d-Pra-ε-Lys is identified using a modified fluorescence protein assay as a highly efficient clickable pyrrolysine mimic. It is shown to incorporate into calmodulin in high yield to provide a handle for labeling with anazide-containing coumarin.
Synthesis, properties and crystal structure of the tripeptide boc-L-prolyl-L-propargylglycyl-glycine methylester

Propargylglycine, as a powerful inhibitor of microbial growth, was built into a protected tripeptide with the sequence Pro-Pra-Gly. The peptide was employed to study its effects on the activity of prolyl 4-hydroxylase and the collagen biosynthesis. The Boc-protected tripeptide methylester was identified by mass spectrometry and NMR spectroscopy and its crystal structure was established by X-ray diffraction analysis.
