Glycine Receptor Activation: When Three Out of Five Is Enough
The prototypic member of the acetylcholine receptor family, the muscle nicotinic receptor, is a heteromeric complex with five subunits but only two ligand-binding sites. However, some members of this receptor superfamily are homomeric, containing five seemingly identical binding sites. Whether activation actually requires binding of five agonist molecules in this situation is unclear. Such ques...
متن کاملFive geranylgeranyl diphosphate synthases expressed in different organs are localized into three subcellular compartments in Arabidopsis.
Geranylgeranyl diphosphate (GGPP) is the precursor for the biosynthesis of gibberellins, carotenoids, chlorophylls, isoprenoid quinones, and geranylgeranylated proteins in plants. There is a small gene family for GGPP synthases encoding five isozymes and one related protein in Arabidopsis, and all homologs have a putative localization signal to translocate into specific subcellular compartments...

متن کاملDissecting the square into five congruent parts
We give an affirmative answer to an old conjecture proposed by Ludwig Danzer: there is a unique dissection of the square into five congruent convex tiles. 2010 Mathematics Subject Classification: 52C20 Introduction and notation In the eighties of the last century, Ludwig Danzer conjectured in several conferences that there is a unique dissection of the square into five congruent parts—see Figur...
متن کاملA Three and Five Color Theorem
Let / be a face of a plane graph G. The Three and Five Color Theorem proved here states that the vertices of G can be colored with five colors, and using at most three colors on the boundary of /. With this result the well-known Five Color Theorem for planar graphs can be strengthened, and a relative coloring conjecture of Kainen can be settled except for a single case which happens to be a par...
