Crystal structure of human CK2α at 1.06 Å resolution
The Ser/Thr kinase CK2 consists of two catalytic subunits (CK2α) and a dimer of the regulatory subunits (CK2β), and is a ubiquitous enzyme that regulates growth, proliferation and the survival of cells. CK2 is a remarkable drug target for potentially treating a wide variety of tumours and glomerulonephritis. The purified CK2α protein was crystallized using ethylene glycol as a precipitant. The ...
متن کاملStructure of human R-state aquomethemoglobin at 2.0 Å resolution.
The crystal structure of tetrameric (αβ)(2) R-state human adult aquomethemoglobin is reported at 2.0 Å resolution. The asymmetric unit contained one αβ subunit pair. The R-state crystal belonged to space group P4(1)2(1)2, with unit-cell parameters a = b = 53.6, c = 192.8 Å. An Fe-bound water molecule was modeled into the heme distal pockets of each of the α and β subunits. In the α subunit, a h...
متن کاملStructure of Sputnik, a virophage, at 3.5-Å resolution.
"Sputnik" is a dsDNA virus, referred to as a virophage, that is coassembled with Mimivirus in the host amoeba. We have used cryo-EM to produce an electron density map of the icosahedral Sputnik virus at 3.5-Å resolution, sufficient to verify the identity of most amino acids in the capsid proteins and to establish the identity of the pentameric protein forming the fivefold vertices. It was also ...
متن کاملStructure of the human 26S proteasome at a resolution of 3.9 Å.
Protein degradation in eukaryotic cells is performed by the Ubiquitin-Proteasome System (UPS). The 26S proteasome holocomplex consists of a core particle (CP) that proteolytically degrades polyubiquitylated proteins, and a regulatory particle (RP) containing the AAA-ATPase module. This module controls access to the proteolytic chamber inside the CP and is surrounded by non-ATPase subunits (Rpns...
متن کاملThe structure of the eukaryotic ribosome at 3.0 Å resolution.
Ribosomes translate genetic information encoded by messenger RNA into proteins. Many aspects of translation and its regulation are specific to eukaryotes, whose ribosomes are much larger and intricate than their bacterial counterparts. We report the crystal structure of the 80S ribosome from the yeast Saccharomyces cerevisiae--including nearly all ribosomal RNA bases and protein side chains as ...
