Channel enzymes represent a class of ion channels with enzymatic activity directly or indirectly linked to their channel function. We investigated a TRPM2 chanzyme from choanoflagellates that integrates two seemingly incompatible functions ...

Eukaryotic translation initiation factor (eIF)4A-a DEAD-box RNA-binding protein-plays an essential role in translation initiation. Recent reports have suggested helicase-dependent and helicase-independent functions for eIF4A, but the multif...
To slide or not to slide: key role of the hexasome in chromatin remodeling revealed [0.03%]

Hexasomes are non-canonical nucleosomes that package DNA with six instead of eight histones. First discovered 40 years ago as a consequence of transcription, two near-atomic-resolution cryo-EM structures of the hexasome in complex with the ...
RNAi screens identify HES4 as a regulator of redox balance supporting pyrimidine synthesis and tumor growth [0.03%]
RNA干扰筛选鉴定出HES4是调节支持嘧啶合成和肿瘤生长的氧化还原平衡的调控因子

NADH/NAD+ redox balance is pivotal for cellular metabolism. Systematic identification of NAD(H) redox regulators, although currently lacking, would help uncover unknown effectors critically implicated in the coordination of growth metabolis...
Structure and mechanism of lysosome transmembrane acetylation by HGSNAT [0.03%]
HGSNAT介导的溶酶体跨膜乙酰化的作用方式和机制研究

Lysosomal transmembrane acetylation of heparan sulfates (HS) is catalyzed by HS acetyl-CoA:α-glucosaminide N-acetyltransferase (HGSNAT), whose dysfunction leads to lysosomal storage diseases. The mechanism by which HGSNAT, the sole non-hyd...

To prevent detrimental chromosome re-replication, DNA loading of a double hexamer of the minichromosome maintenance (MCM) replicative helicase is temporally separated from DNA unwinding. Upon S-phase transition in yeast, DNA unwinding is ac...
The LexA-RecA* structure reveals a cryptic lock-and-key mechanism for SOS activation [0.03%]
LexA-RecA* 结构揭示了触发SOS反应的隐秘锁钥机制

The bacterial SOS response plays a key role in adaptation to DNA damage, including genomic stress caused by antibiotics. SOS induction begins when activated RecA*, an oligomeric nucleoprotein filament that forms on single-stranded DNA, bind...
