The presence of a turn of 310 helix in the middle of the T-loop suggests that secondary structure could form when it interacts with soluble receptor enzymes. Co-crystals of GlnK and ATP were used to determine the structure of the complex. In these crystals, GlnK occupies a position of 3...
Structure of the MORC4 ATPaseCW cassette To gain mechanistic insight into the MORC4 activation process, we crystallized ATPaseCW (aa 29–486 of human MORC4) in complex with the non-hydrolyzable ATP analog, adenylyl-imidodiphosphate (AMPPNP), collected and analyzed X-ray crystallographic data, an...

研究人员首先通过生化实验证明Csm复合物可以将ATP分子合成为cAn,并证明其主要产物cA4为激活Csm6的效应分子,并且解析了3.2 Å Csm 复合物与ATP底物类似物AMPPNP 的电镜结构, 2.9Å Csm 复合物与产物cA4的电镜结构(图2)以及Csm1-Csm4与...
Furthermore, the newly prepared complexes exhibit nano-structural characteristics, which were measured by SEM and X-Ray diffraction of the powder. SEM data showed that complexes from (3, 5) and (8) gave irregular nano-structure, nano-rod structure, and nano-sphere structural pattern respectively...
The interaction of ATP with the active site of hexokinase is unknown since the crystal structure of the hexokinase-ATP complex is unavailable. It was found that the ATP binding site of brain hexokinase is homologous to that of actin, heat shock protein hsc70, and glycerol kinase. On the basi...
The GPIT complex is known to be composed of five subunits: PIGK, PIGU, PIGT, PIGS and GPAA1. Here, we determined the structure of the human GPIT complex at a resolution of 3.1 Å using single-particle cryo-EM, elucidating its overall assembly. The PIGK subunit functions as the ...
