See detailΔ2- and Δ3-Cephalosporins, penicillinate, and 6-unsubstituted penems. Intrinsic reactivity and interaction with β-lactamases and D-alanyl-D-alanine-cleaving serine peptidases
Frère, Jean-Marie ULg; Kelly, Judith A; Klein, Daniel et al

in Biochemical Journal (1982), 203(1), 223-234

The intrinsic reactivity of delta 2- and delta 3-deacetoxy-7-phenylacetamidocephalosporanates, penicillanate, unsubstituted, 2-methyl- and 2-phenyl-penems and other beta-lactam antibiotics has been expressed in terms of the second-order rate constant (M-1.s-1(OH-)) for the hydrolysis of the beta-lactam amide bond by OH- at 37 degrees C. The values thus obtained have been compared with the second-order rate constants (M-1.s-1(enzyme) for the opening of the same beta-lactam amide bond during interaction with the beta-lactamases of Streptomyces albus G and Actinomadura R39 and the D-alanyl-D-alanine-cleaving serine peptidases of Streptomyces R61 and Actinomadura R39. Depending on the cases, the accelerating effect due to enzyme action and expressed by the ratio M-1.s-1(enzyme)/M-1.s-1(OH) varies from less than 2 to more than 1 x 10(6). The primary parameter that governs enzyme action is the goodness of fit of the beta-lactam molecule to the enzyme cavity rather than its intrinsic reactivity. With the D-alanyl-D-alanine-cleaving serine peptidases, the three penems studied form intermediate complexes characterized by very short half lives of 14-100 s, values significantly lower than those exhibited by most beta-lactam compounds.

Les Ἐρωτικὰ Παθήματα de Parthénios de Nicée est l’unique œuvre conservée d’un auteur grec aujourd’hui peu connu malgré son évident succès au Ier siècle av. J.-C. Cet écrivain lettré originaire de Nicée, ramené comme esclave à Rome lors des guerres contre Mithridate puis libéré grâce à son talent littéraire était surtout apprécié pour sa poésie. Le hasard de la tradition manuscrite ne nous a cependant transmis que ce petit recueil en prose dédié au célèbre poète latin, Cornélius Gallus. L’opuscule a l’originalité de rassembler trente-six résumés d’histoire d’amour à l’issue malheureuse voire tragique. Au fil des récits, l’auteur raconte les conséquences funestes d’émotions démesurées comme la folie amoureuse sur les protagonistes, symboles du genre humain. Sur base d’une analyse philologique et sémantique minutieuse, l’exposé aura donc pour but de présenter le traitement littéraire de la passion et de son opposé, la raison dans cet ouvrage si particulier de Parthénios.

The γ Cas category is a subgroup of Be stars displaying a strong, hard, and variable thermal X-ray emission. An XMM-Newton observation of π Aqr reveals spectral and temporal characteristics that clearly make this Be star another member of the γ Cas category. Furthermore, π Aqr is a binary but, contrary to γ Cas, the nature of the companion to the Be star is known; it is a non-degenerate (stellar) object and its small separation from the Be star does not leave much room for a putative compact object close to the Be disk. This renders the accretion scenario difficult to apply in this system, and, hence, this discovery favors a disk-related origin for the γ Cas phenomenon. Based on observations collected with the ESA science mission XMM-Newton, an ESA Science Mission with instruments and contributions directly funded by ESA Member States and the USA (NASA). [less ▲]
