    ..coli seems to use Arg-153 from a region termed Lid instead. Thus, the binding of AZT-MP to the yeast TmpK results in the shift of a catalytic residue, which is not the case for the bacterial kinase...

    ..Our studies shed light on the structural and functional organization of a highly divergent kinetochore particle. ..

    ..Our study reveals structural and quantitative differences between the homodimeric interactions of the three mouse PERIOD homologues, which are likely to contribute to their distinct clock functions. ..

    ..Here, we describe purification methods of the different factors employed and chromatography techniques that yield highly specific complex assemblies suitable for crystallization. ..

    ..Our results indicate that the Hsp70-chaperone network that is present in the pancreatic ER is even more complex than previously thought, and suggest that the pancreatic rER has a significant capacity for protein degradation...

    ..In addition, we identify the PAS-B beta-sheet surface as a versatile interaction site mediating mPER2 homodimerization in the mammalian system and dPER-dTIM heterodimer formation in the Drosophila system. ..
