Cyanobacterial pilin was extracted from Synechococcus 6301 membranes using a detergent mixture comprising 1% Triton X-100, 1% Thesit and 0.5% dodecyl beta-D-maltoside. Partial purification of pilin from the crude extract was achieved by a single-step purification applying the Rotofor isoelectric

Supplementation of 5% phenylalanine plus 0.4% alpha-methylphenylalanine to the standard diet or 1% phenylalanine plus 0.08% alpha-methylphenylalanine to the drinking water produced phenylketonuria-like conditions in 5-day-old chicks. An increase of 10 to 15-fold in the phenylalanine content was observed in
We have synthesized, by solution methods, and fully characterized a variety of (alpha Me)Phe derivatives and model peptides (to the pentapeptide level). The results of the solution conformational analysis, performed by using infrared absorption and 1H nuclear magnetic resonance, support

Previous work has shown that incorporation of either 1-aminocyclohexanecarboxylic acid (Ac6c) or alpha-methyl-p-phosphonophenylalanine ((alpha-Me)Ppp) in the phosphotyrosyl (pTyr) C-proximal position (pY + 1 residue) of Grb2 SH2 domain binding peptides confers high affinity. The tetralin-based (S)-2-amino-6-phosphonotetralin-2-carboxylic acid (Atc(6-PO3H2)) simultaneously presents
