A procedure allowing the purification of milligram amounts of the exocellular dd-carboxypeptidase-transpeptidase from Streptomyces R61 to protein homogeneity (95% purity) is described. The isolated protein has a molecular weight of about 38000 and consists of one polypeptide chain. Its amino acid composition is presented. [less ▲]

Monodisperse polystyrenes (PS) of different molecular weights (Mn) synthesized by living anionic polymerization with three types of butyllithium initiator (linear, n; secondary, sec; and tertiary, tert) were analyzed by ToF-SIMS (time-of-flight secondary ion mass spectrometry). The influence of the molecular weight on the secondary ion intensities was studied in detail for the fingerprint part of the mass spectra (with m/z < 200). A drastic effect was observed for Mn values below 104, related to the presence of the saturated butyl end group. An extra hydrogen transfer originating from this end group during the secondary ion formation must be invoked to explain the data. Only the first neighbor monomer repeat units seem to be affected. This H exchange increases the intensity of ions containing more hydrogen or needing H transfer for their formation as the tropylium ion (C7H7+ at m/z = 91). The molecular structure of the butyl end group is found to influence greatly not only the intensity of their parent ion but also the PS characteristic ion intensities. Indeed, the tert-butyl end group is seen unable to produce the H transfer observed for the n- and sec-butyl ones. A model is proposed to take the influence of the end group on the PS SIMS fragmentation pattern into account. The parameters of this model allow the quantification of the end group interaction.

The exocellular dd-carboxypeptidase-transpeptidase from Streptomyces R39 was purified to protein homogeneity and in milligram amounts. The isolated enzyme consisted of one polypeptide chain of molecular weight about 53300. Its amino acid composition and several physicochemical properties were determined and compared with those of the exo-cellular dd-carboxypeptidase-transpeptidase from Streptomyces R61. [less ▲]

The molecular orientation in self-assembled monolayers of thiophenol (TP) on Ag(1 1 1) and of para-nitroanilinododecane-thiol (NAT) on Au was investigated by infrared-visible sum-frequency generation between 500 and 1500 cm-1. Ab initio calculations were performed to determine the interface nonlinear response. The combined experimental and theoretical results reveal that the S–C bond of TP is tilted 37° from the Ag(1 1 1) surface normal, with the aromatic ring plane perpendicular to the surface. On Au, the tilt angle of the NAT molecule stabilizes below 60° at the end of film growth. [less ▲]

A single molecule logic gate using electronically excited states and ionization/fragmentation can take advantage of the differences in cross-sections for one and two photon absorption. Fault tolerant optically pumped half adder and full adder are discussed as applications. A full adder requires two separate additions, and the logic concatenation that is required to implement this is physically achieved by an intramolecular transfer along the side chain of 2-phenylethyl-N,N-dimethylamine (PENNA). Solutions of the kinetic equations for the temporal evolution of the concentration of different states in the presence of time-varying laser fields are used to illustrate the high contrast ratios that are potentially possible for such devices.

The placenta of ruminant contains binucleate trophoblastic cells synthesizing proteins, migrating cross the barrier and fusing with endothelial cells of the endometrium. Recently described were two glycoproteins from the family of aspartic proteases, apparently lacking the enzymatic activity: the pregnancy associated glycorproteins I and II (PAGI and PAGII). The first (PAGI) is largely secreted in maternal blood, this characteristic copes with the lack of proteolytic activity. The second (PAGII) is not completely characterized. However, it binds to lutropin (LH) receptors with high affinity. This binding allows to assume that PAGII is likely the same as the bovine chorionic gonadotropin identified earlier (bCG). A better characterization of these glycoproteins (PAGI and PAGII) and other members of the family (PAGIII...) will answer these questions together with the unexplained invasive process of the placenta.

La valorisation de la lignine, dans le cadre de la bioraffinerie lignocellulosique du futur, est une thématique particulièrement prometteuse. En effet, la lignine est la principale matière première renouvelable composée de motifs aromatiques. Ce polymère est le plus souvent valorisé uniquement par combustion dans les papeteries pour la production d’énergie. La mise en route de bioraffineries destinées à convertir la biomasse lignocellulosique en carburants de transport générera en général plus de lignine que nécessaire pour alimenter l’installation en énergie2. Dès lors, des efforts sont en cours pour transformer la lignine en produits à valeur ajoutée. Sa valorisation en composés aromatiques de bas poids moléculaires (tels que benzène, toluène, xylènes: BTX) permettrait une plus-value considérable dans la mesure où les BTX sont des molécules de base de la pétrochimie et représentent en 2015 un marché de 100 milliards de dollars3. On estime généralement que l’étude de la valorisation de la cellulose en particulier en éthanol a eu lieu il y a 20 ans, celle de la valorisation des hémicelluloses il y a 10 ans et celle de la valorisation de la lignine a lieu actuellement.

It makes part of a larger project (called the MOLIERE project) undertaken by eleven European countries gathered to analyse restructurings.
