Qualitative and quantitative composition of isolated peptidoglycan indicate an Aly-type. meso-Diaminopimelic acid was the only diamino acid found. Direct cross-linkage of peptide sidechains was confirmed by separation of respective dipeptides (M-A;pm-D-Ala) from partial acid hydrolysates of ...
Little is known about the molecular basis of the biological activity. The chemical composition is at least important for the antigenic determinants. The lysozyme susceptibility and the size of the preparation may be other crucial points for the biological activity of the peptidoglycan. 展开 ...

It is known that MurF is essential during the last step in the biosynthesis of monomeric precursor of peptidoglycan within peptidoglycan biosynthesis since it adds (in an ATP-dependent manner) D-Ala-D-Ala dipeptide to UDP-N-acetylmuramyl-L-Ala-γ-D-Glu-m-DAP. What makes MurF became an ...
Over the past decade, the great impact of agricultural crop diseases has generated considerable economic losses and has compromised the production of edible crops at a time when the world population is only expected to rise, leading to the search for new
This study aimed at investigating the chemical composition and microstructure of spray dried camel and cow milk powders' surfaces with two different milk-fat contents (1 and 20g 100 g−1). The SEM (Scanning Electron Microscopy) micrographs showed that spherical particles with a ‘brain’-type ...
aureus, by the addition of 5 glycine residues, catalyzed by FemXAB enzymes; such interpeptide bridges occur in most Gram-positive bacteria, but may vary in composition and length. Finally, lipid II is translocated across the membrane by an unknown mechanism, of which both SAV1754 and FtsW ...

respectively. The three gene encode UDP-N-acetylenolpyruvoylglucosamine reductase (peptidoglycan precursor biosynthesis), two-component response regulator (cell wall metabolism control) and phosphatidate cytidylyltransferase (phospholipids biosynthesis), respectively. Precise regulation of the expression levels of ...
