Epicuticular Factors Involved in Host Recognition for the Aphid Parasitoid Aphidius rhopalosiphi

In insect parasitoids, fitness is dependent on the host finding and recognition abilities of the female. Host recognition cues have been described for various host–parasitoid systems, but are still under investigation in aphid parasitoids. Our study aimed to clarify the respective role of physical and chemical cues in recognition of the aphid cuticle. Shed aphid exuviae were used as an elicitor in order to avoid any influence of color, movement, or volatiles present in a living aphid. We assessed the effect of chemical and heat treatments on the texture of the cuticle by using scanning electron microscopy and tested the recognition of treated cuticles by the parasitoid. We showed that recognition cues of the cuticle can be removed chemically (using combined treatments with n-hexane and methanol). Moreover, heat treatment destroyed the physical texture of the cuticle without significantly reducing parasitoid recognition. In a second step, we showed that epicuticular extracts deposited on pieces of paper triggered female attack behavior. First results concerning the chemical composition of the active extract are presented. This study shows that chemical compounds extractable by organic solvents mediate cuticle recognition by aphid parasitoids.

Enantioselective Gas Chromatography with Derivatized Cyclodextrins in the Flavour and Fragrance Field

This article deals with enantioselective gas chromatography (Es-GC) utilizing cyclodextrin derivatives as chiral stationary phases (CSPs) for chiral recognition in the flavour and fragrance field. It consists of two main parts. The first one concerns cyclodextrins and their use in Es-GC, and it deals with their introduction and evolution as CSPs in GC, together with some theoretical aspects involved with enantiomeric separation and their consequent influence on routine chiral recognition. The second part reports on the strategy of chiral recognition in routine analysis with cyclodextrin derivatives as CSP, illustrated with examples from the authors’ everyday experiences. This part describes how to identify enantiomers or to measure their excess or ratio determination in complex mixtures; in particular, it discusses the opportunities offered by multidimensional and fast GC techniques, the role of mass spectrometry, and the application of total analysis systems to chiral recognition.

Inhibition studies of porphobilinogen synthase from Escherichia coli differentiating between the two recognition sites

Porphobilinogen synthase condenses two molecules of 5-aminolevulinate in an asymmetric way. This unusual transformation requires a selective recognition and differentiation between the substrates ending up in the A site or in the P site of porphobilinogen synthase. Studies of inhibitors based on the key intermediate first postulated by Jordan allowed differentiation of the two recognition sites. The P site, whose structure is known from X-ray crystallographic studies, tolerates ester functions well. The A site interacts very strongly with nitro groups, but is not very tolerant to ester functions. This differentiation is a central factor in the asymmetric handling of the two identical substrates. Finally, it could be shown that the keto group of the substrate bound at the A site is not only essential for the recognition, but that an increase in electrophilicity of the carbon atom also increases the inhibition potency considerably. This has important consequences for the recognition process at the A site, whose exact structure is not yet known.

Computer modelling of the interaction between human choriogonadotropin and its receptor

Primary structural homology between the hormone binding siteof the LH/CG receptor and the enzyme binding site of chymotrypsininhibitor has been identified. This has led to the applicationof a knowledge-based approach of molecular modelling to describethe interaction of choriogonadotropin (CG) with the LH/CG receptor.A tertiary structural model for the mode of recognition betweenthe hormone and the receptor has been proposed. As in othersuch processes at the molecular level, the recognition betweenCG and its receptor is mediated through non-covalent interactions.The specificity of recognition is achieved by complementarityin van der Waals surfaces, hydrogen bonding and non-polar associations.The model shows nine hydrogen bonds between the hormone andthe receptor involving polar side chains as well as backboneamine and carbonyl groups. A hydropbobic cluster involving sidechain groups at the interface is also important in stabilizationof the intermolecular interactions
