    Lysine stimulation of cephalosporin C synthesis in Cephalosporium acremonium (1979)
    Springer

    Notes: Summary Lysine added to a defined medium at a concentration of 1 mg/ml enhances the capacity of Cephalosporium acremonium to produce cephalosporin C. The lysine effect was accompanied by a delayed differentiation to arthrospores followed by more extensive mycelial fragmentation. Higher lysine concentrations reduced the synthesis of cephalosporin C. The effect of lysine on cephalosporin C synthesis was not strain related and was not elicited by the other amino acids tested. Both lysine stimulation and inhibition were evidenct using resting cells. The lysine inhibition of cephalosporin C synthesis with resting cells was relieved by supplementing the medium with 1 to 2 mg/ml α-aminoadipic acid. This reversal supports the hypothesis that lysine restricts the availability of α-aminoadipic acid for β-lactam biosynthesis.

    Notes: Zusammenfassung Untersuchungen derr II-Region desT 2-Bakteriophagen. Es wurde eine genetische Analyse derr II-Region desT 2-Bakteriophagen durchgeführt zur Feststellung, ob die Befunde, die sich auf die Funktionsteile innerhalb derr II-Region desT 4-Phagen beziehen, in bezug auf dier II-Region desT 2-Phagen verallgemeinert werden können. Die Mutanten wurden mit Hilfe von 5-Bromouracil und Akridineorange isoliert und dieh + r-Mutanten nach demselben Schema wie fürT 4-Phagen weiter differenziert. Sechzig ausgewählte Mutanten wurden nach funktionaler Identität geprüft, was zur Feststellung führte, dass die gesamte Region als eine Einheit funktioniert.

    Fungitoxicity ofm-fluorophenylalanine-containing peptides towardsPythium ultimum (1989)
    Springer
    Cellular and molecular life sciences 45 (1989), S. 325-327 
    Details
    ISSN: 1420-9071
    Keywords: Amino acid transport ; fluorophenylalanine ; peptide transport ; Pythium ultimum

    Notes: Summary The tripeptide L-m-fluorophenylalanyl-L-alanyl-L-alanine was much more fungitoxic towardsPythium ultimum than the dipeptide L-m-fluorophenylalanyl-L-alanine orm-fluorophenylalanine. The fungitoxicity of the tripeptide was reduced by L-alanyl peptides and phenylalanine, but not by other amino acids. In contrast, the fungitoxicity ofm-fluorophenylalanine was unaffected by peptides, and was antagonized by several amino acids. These results suggest the effective delivery ofm-fluorophenylalanine into the cell by a tripeptide carrier.

    Actinomycin D inactivating enzymes fromActinoplanes missouriensis and several other members of theActinoplanaceae family (1978)

    Notes: Summary The enzymes for inactivating actinomycin D appear to be widely distributed amongst species belonging to the familyActinoplanaceae. Actinomycin D was completely or partially inactivated by cell-free extracts fromActinoplanes missouriensis, Streptosporangium viridogriseum, S. violaceocbromogenes, S. roseum, S. brasiliense, S. albidum, Spirillospora sp.,Sp. albida, Kitasatoa kauaiensis, Planobispora longispora, P. rosea, Dactylosporangium aurantiacum, andD. thailandense. No inactivation was obtained with extracts fromAmorphosphorangium auranticolor, Ampullariella lobata, Planomonospora parontospora, andP. venezuelensis. Actinomycin lactonase was partially purified by ultracentrifugation, ultrafiltration, and isoelectric focusing from noninduced cells ofActinoplanes missouriensis. The enzyme has a molecular weight of greater than 200,000 daltons and an isoelectric point of 4.3 to 4.4.
