This study characterized Clavispora lusitaniae strains isolatedfrom different stages of the processing and early fermentationof a henequen (Agave fourcroydes) spirit produced inYucatan, Mexico using a molecular technique. Sixteen strainsidentified based on morphological features, obtained fromdifferent substrates, were typed molecularly. Nine differentversions of the divergent D1/D2 domain of the large-subunitribosomal DNA sequence were identified among theC. lusitaniae strains. The greatest degree of polymorphismwas found in the 90-bp structural motif of the D2 domain. The MSP-PCR technique was able to differentiate 100% ofthe isolates. This study provides significant insight into thegenetic diversity of the mycobiota present during the henequenfermentation process, especially that of C. lusitaniae,for which only a few studies in plants have been published. The applied MSP-PCR markers were very efficient in revealingpolymorphisms between isolates of this species.

<P><B>Motivation:</B> Many genomes have been completely sequenced. However, detecting and analyzing their protein–protein interactions by experimental methods such as co-immunoprecipitation, tandem affinity purification and Y2H is not as fast as genome sequencing. Therefore, a computational prediction method based on the known protein structural interactions will be useful to analyze large-scale protein–protein interaction rules within and among complete genomes.</P><P><B>Results:</B> We confirmed that all the predicted protein family interactomes (the full set of protein family interactions within a proteome) of 146 species are scale-free networks, and they share a small core network comprising 36 protein families related to indispensable cellular functions. We found two fundamental differences among prokaryotic and eukaryotic interactomes: (1) eukarya had significantly more hub families than archaea and bacteria and (2) certain special hub families determined the topology of the eukaryotic interactomes. Our comparative analysis suggests that a very small number of expansive protein families led to the evolution of interactomes and seemed tohave played a key role in species diversification.</P><P><B>Contact:</B> jong@kribb.re.kr</P><P><B>Supplementary information:</B> http://interactomics.org</P>
When humanoid robots become human-like interaction partners: Corepresentation of robotic actions.
Stenzel, Anna,Chinellato, Eris,Bou, Maria A. Tirado,del Pobil, Á,ngel P.,Lappe, Markus,Liepelt, Roman American Psychological Association 2012 JOURNAL OF EXPERIMENTAL PSYCHOLOGY-HUMAN PERCEPTIO Vol.38 No.5
<P>In human-human interactions, corepresenting a partner's actions is crucial to successfully adjust and coordinate actions with others. Current research suggests that action corepresentation is restricted to interactions between human agents facilitating social interaction with conspecifics. In this study, we investigated whether action corepresentation, as measured by the social Simon effect (SSE), is present when we share a task with a real humanoid robot. Further, we tested whether the believed humanness of the robot's functional principle modulates the extent to which robotic actions are corepresented. We described the robot to participants either as functioning in a biologically inspired human-like way or in a purely deterministic machine-like manner. The SSE was present in the human-like but not in the machine-like robot condition. These findings suggest that humans corepresent the actions of nonbiological robotic agents when they start to attribute human-like cognitive processes to the robot. Our findings provide novel evidence for top-down modulation effects on action corepresentation in human-robot interaction situations.</P>

<P><B>Summary:</B> Protein Structural Interactome map (PSIMAP) is a global interaction map that describes domain–domain and protein–protein interaction information for known Protein Data Bank structures. It calculates the Euclidean distance to determine interactions between possible pairs of structural domains in proteins. PSIbase is a database and file server for protein structural interaction information calculated by the PSIMAP algorithm. PSIbase also provides an easy-to-use protein domain assignment module, interaction navigation and visual tools. Users can retrieve possible interaction partners of their proteins of interests if a significant homology assignment is made with their query sequences.</P><P><B>Availability:</B> http://psimap.org and http://psibase.kaist.ac.kr/</P><P><B>Contact:</B> biopark@kaist.ac.kr</P><P><B>Supplementary information:</B> Supplementary material is available at http://psibase.kaist.ac.kr/Doc/supplementary_material.htm</P>

<P>In this paper, we show that the onset potential for CO oxidation electrocatalyzed by ∼2 nm dendrimer-encapsulated Pt nanoparticles (Pt DENs) is shifted negative by ∼300 mV in the presence of a small percentage (<2%) of Cu surface atoms. Theory and experiments suggest that the catalytic enhancement arises from a cocatalytic Langmuir–Hinshelwood mechanism in which the small number of Cu atoms selectively adsorb OH, thereby facilitating reaction with CO adsorbed to the dominant Pt surface. Theory suggests that these Cu atoms are present primarily on the (100) facets of the Pt DENs.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/ancac3/2016/ancac3.2016.10.issue-9/acsnano.6b04448/production/images/medium/nn-2016-04448k_0008.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nn6b04448'>ACS Electronic Supporting Info</A></P>
