Two oligopeptides containing phosphinothricin were accumulated in the culture of bialaphos (BA) producer Streptomyces hygroscopicus SF1293 when large amount of BA was added to the culture at idio phase. One of the oligopeptides was a new substance, BA dimer (phosphinothricyl-alanyl-alanyl-phosphinothricyl-alanyl-alan ine), and the other was a known substance called If (phosphinothricyl-alanyl-a...

The line shapes detected in coherent femtosecond vibrational spectroscopies contain direct signatures of peptide conformational fluctuations through their effect on vibrational frequencies and intermode couplings. These effects are simulated in trialanine using a Green's function solution of a stochastic Liouville equation constructed for four collective bath coordinates (two Ramachandran angle...

Beta-lactamase induction in Enterobacter cloacae, which is linked to peptidoglycan recycling, was investigated by high-performance liquid chromatographic analysis of cell wall fragments in genetically defined cells of Escherichia coli. After treatment of cells with beta-lactams, we detected an increase in a D-tripeptide (disaccharide-tripeptide, N-acetylglucosaminyl-1,6-anhydro-N-acetylmuramyl-...

Pressure-induced oligomerization was found from high-pressure experiments at 25 °C on alanine powder soaked in its saturated aqueous solution. The oligomerization to alanylalanine occurred at 5 GPa. The maximum yields of alanylalanine and trialanine were, respectively, 1.1 × 10(-3) and 1.3 × 10(-4) at 11 GPa.
