“…5,7 Table 4 shows the elution volume and recovery of peptides on Ether-5PW. As a result, actinomycin C was not eluted out nor recovered at all from Phenyl-5PW, which suggests that this peptide is higher in the hydrophobic property than general proteins, presumably due to its phenoxazone moiety, and the moiety may strongly interact with phenylfunctional groups in the packings.…”

Chromatographic behaviors of amino acids and peptide derivatives were examined by high performance hydrophobic interaction chromatography(HIC) on two different packings, TSKgels Phenyl-5PW and Ether-5PW. Most amino acids hardly retained and eluted at an elution volume being the same as the column volume even with an initial buffer for hydrophobic interaction chromatography; aromatic amino acids showed weak retention. On the other hand, peptides retained in the column and their elution was roughly in the order of the molecular mass, although some of them showed extraordinary elution behaviors. Kunitz bovine pancreas trypsin inhibitor showed weak retention in spite of having larger molecular mass, which might be due to the steric conformation. Downloaded by [University of Western Ontario] at 10:44 16 November 2014 ORDER REPRINTS 1966 YAMASAKI ET AL.Some peptides showed considerably stronger retention even under ordinary conditions, and the addition of organic modifier (20 % acetonitrile) in eluent was required for their elution. HIC using less hydrophobic packings examined was found to be adequate to separate peptides quantitatively, and this might be useful in removing peptides from contaminants of amino acids and proteins.

The synthesis of ten new thyrotropin‐releasing hormone analogues (15–24) which contain uncoded amino acids (L‐ and D‐homoleucine, L‐ and D‐homophenylalanine, L‐homoproline and 6‐ketopipecolic acid) is described here. The peptide bond formation was achieved in solution phase using pentafluorophenyl ester activation of the N‐protected amino acids. The analogues were tested for their ability to release thyrotropin and for CNS activities and proved to be fully inactive.

“…31) Crystallographic and sitedirected mutagenesis studies of halophilic enzymes have revealed the mechanisms of hallophilicity. Malate dehydrogenase from Halobacterium marismortui is an active tetramer above 2 M NaCl or KCl, but an inactive monomer below 2 M, and the binding of Lys205 with a chloride ion is responsible for dimerization.…”
