Identifying sequence-structure pairs undetected by sequence alignments.
We examine how effectively simple potential functions previously developed can identify compatibilities between sequences and structures of proteins for database searches. The potential function consists of pairwise contact energies, repulsive packing potentials of residues for overly dense arrangement and short-range potentials for secondary structures, all of which were estimated from statist...
متن کاملA wide diversity of previously undetected free-living relatives of diplomonads isolated from marine/saline habitats.
Over the last 15 years classical culturing and environmental PCR techniques have revealed a modest number of genuinely new major lineages of protists; however, some new groups have greatly influenced our understanding of eukaryote evolution. We used culturing techniques to examine the diversity of free-living protists that are relatives of diplomonads and retortamonads, a group of evolutionary ...
متن کاملDirect visualization of alpha-synuclein oligomers reveals previously undetected pathology in Parkinson’s disease brain
Oligomeric forms of alpha-synuclein are emerging as key mediators of pathogenesis in Parkinson's disease. Our understanding of the exact contribution of alpha-synuclein oligomers to disease is limited by the lack of a technique for their specific detection. We describe a novel method, the alpha-synuclein proximity ligation assay, which specifically recognizes alpha-synuclein oligomers. In a bli...
متن کاملAffinity labeling of a previously undetected essential lysyl residue in class I fructose bisphosphate aldolase.
The affinity label N-bromoacetylethanolamine phosphate (BrAcNHEtOP) has been used previously at pH 6.5 to identify His-359 of rabbit muscle aldolase as an active site residue. We now find that the specificity of the reagent is pH-dependent. At pH 8.5, alkylation with 14C-labeled BrAcNHEtOP abolishes both fructose-1,6-P2 cleavage activity and transaldolase activity. The stoichiometry of incorpor...
متن کاملStatistical analysis of COMPTEL maximum likelihood-ratio distributions: evidence for a signal from previously undetected AGN
The maximum likelihood-ratio method is frequently used in COMPTEL analysis to determine the signiicance of a point source at a given location. In this paper we do not consider whether the likelihood-ratio at a particular location indicates a detection, but rather whether distributions of likelihood-ratios derived from many locations depart from that expected for source free data. We have constr...
