Flexibility of Subdivided Polyhedral Complexes
A subdivided polyhedron is the graph obtained by adding vertices on some of the edges of the 1-skeleton of a polyhedron. We also consider subdivided polyhedral complexes, which are collections of polyhedra connected into a topological complex along faces (as in a beehive). We use these graphs to define abstract molecules, by placing atoms at the vertices and bonds along the edges. One of the si...
متن کاملStructural and evolutionary versatility in protein complexes with uneven stoichiometry.
Proteins assemble into complexes with diverse quaternary structures. Although most heteromeric complexes of known structure have even stoichiometry, a significant minority have uneven stoichiometry--that is, differing numbers of each subunit type. To adopt this uneven stoichiometry, sequence-identical subunits must be asymmetric with respect to each other, forming different interactions within ...
متن کاملpredictions of protein-protein interfaces within membrane protein complexes
background: prediction of interaction sites within the membrane protein complexes using the sequence data is of a great importance, because it would find applications in modification of molecules transport through membrane, signaling pathways and drug targets of many diseases. nevertheless, it has gained little attention from the protein structural bioinformatics community. methods: in this stu...
متن کاملEvolutionary complexity of MADS complexes.
Developmental programs rely on the timely and spatially correct expression of sets of interacting factors, many of which appear to be transcription factors. Examples of these can be found in the MADS-box gene family. This gene family has greatly expanded, particularly in plants, by a range of duplications that have enabled the genes to diversify in structure and function. MADS-box genes appear ...
متن کاملAccurate nanoscale flexibility measurement of DNA and DNA–protein complexes by atomic force microscopy in liquid
The elasticity of double-stranded DNA (dsDNA), as described by its persistence length, is critical for many biological processes, including genomic regulation. A persistence length value can be obtained using atomic force microscopy (AFM) imaging. However, most AFM studies have been done by depositing the sample on a surface using adhesive ligands and fitting the contour to a two-dimensional (2...
