The most common human lymphoid chromosomal translocations involve concurrent failures of the recombination activating gene (RAG) complex and Activation-Induced Deaminase (AID). These are two enzymes that are normally expressed for purposes ...

During protein biosynthesis, ribosomes bind to messenger (m)RNA, locate its protein-coding information, and translate the nucleotide triplets sequentially as codons into the corresponding sequence of amino acids, forming proteins. Non-codin...

Oxygen (O2) is essential for life and therefore the supply of sufficient O2 to the tissues is a major physiological challenge. In mammals, a deficit of O2 (hypoxia) triggers rapid cardiorespiratory reflexes (e.g. hyperventilation and increa...
The AAA+ superfamily: a review of the structural and mechanistic principles of these molecular machines [0.03%]
AAA+超家族:这些分子机器结构和机理原则的回顾

ATPases associated with diverse cellular activities (AAA+ proteins) are a superfamily of proteins found throughout all domains of life. The hallmark of this family is a conserved AAA+ domain responsible for a diverse range of cellular activ...
Causes and consequences of impaired methionine synthase activity in acquired and inherited disorders of vitamin B12 metabolism [0.03%]
获得性和遗传性维生素B12代谢障碍中甲硫氨酸合成酶活性受损的原因和后果

Jean-Louis Guéant et al.
Methyl-Cobalamin (Cbl) derives from dietary vitamin B12 and acts as a cofactor of methionine synthase (MS) in mammals. MS encoded by MTR catalyzes the remethylation of homocysteine to generate methionine and tetrahydrofolate, which fuel met...

The etiology of neurodevelopmental disorders (NDDs) remains a challenge for researchers. Human brain development is tightly regulated and sensitive to cellular alterations caused by endogenous or exogenous factors. Intriguingly, the surge o...
Diverse triterpene skeletons are derived from the expansion and divergent evolution of 2,3-oxidosqualene cyclases in plants [0.03%]
植物中2,3-氧化角鲨烯环化酶的扩展及分歧演化衍生出多种三萜骨架结构

Detailed studies of the Gram-negative model bacterium, Escherichia coli, have demonstrated that post-transcriptional events exert important and possibly greater control over gene regulation than transcription initiation or effective transla...
Regulation of protein function and degradation by heme, heme responsive motifs, and CO [0.03%]
