New species of Aporomyces
Full text linkThree new species of Aporomyces (Laboulbeniomycetes) parasitic on beetles from Ecuador are described. These are A. aequatorialis, parasitic on Byrrhinus near B. plenus (Limnichidae); A. benjaminii, parasitic on Plagiogramma sp. (Histeridae); and A.
maximus, parasitic on Byrrhinus cf. maculatus. A key to all the species in the genus Aporomyces is given
Cesariella, a new genus of Laboulbeniales
No full textCesariella graeca gen. sp. nov. is described to accommodate a new species of the Laboulbeniales (Fungi, Ascomycota) parasitic on the endogean ground beetles Reicheadella aetolica
and R. bischoffi (Coleoptera, Carabidae) from Greece. Cesariella is distinguished from the allied genus Laboulbenia by the presence of two cells borne on the inner side of cell III, and by the presence of a conspicuous remnant of the spore apex protruding laterally near the base of the appendage

Rodaucea, a new genus of the Laboulbeniales
No full textThe new genus Rodaucea is created for a new species of Laboulbeniales parasitic on carrion beetles from Ecuador. The new genus is characterized by the presence of two unequal secondary receptacles flanking cell II on opposite sides. The perithecia have the wall cells arranged in four tiers distinctly unequal in height and the antheridia are phialid-like structures borne terminally on branches of primary and secondary appendages
Uncovering GPCR and G Protein Function by Protein Structure Network Analysis
No full textProtein structure network (PSN) analysis is one of the graph theory-based approaches currently used for investigating structural communication in biomolecular systems. Information on the system's dynamics can be provided by atomistic molecular dynamics (MD) simulations or coarse grained elastic network models paired with normal mode analysis (ENM-NMA). This chapter reports on selected applications of PSN analysis to uncover the structural communication in G protein coupled receptors (GPCRs) and G proteins. Strategies to highlight changes in structural communication caused by mutations, ligand and protein binding are described. Conserved amino acids, sites of misfolding mutations, or ligands acting as functional switches tend to behave as hubs in the native structure networks. Densely linked regions in the protein structure graphs could be identified as playing central roles in protein stability and function. Changes in the communication pathway fingerprints depending on the bound ligand or following amino acid mutation could be highlighted as well. A bridge between misfolding and misrouting could be established in rhodopsin mutants linked to inherited blindness. The analysis of native network perturbations by misfolding mutations served to infer key structural elements of protein responsiveness to small chaperones with implications for drug discovery
