查询词典 amino acids

Following this discovery, a variety of neurotoxins were characterized and their amino acids sequences, secondary structure and tertiary structure were also characterized. These toxins are polypeptides of single chain and consist of 46-49 amino acids, cross-linked by three disulfide bridges. The ordered secondary structure has been determined on the basis of NMR studies. The dominant feature is a four-stranded anti-parallel β-sheet, linked with three loop.

Hydrolysis of the mischarged amino acids in theediting reaction will rely on the proper binding and correct recognition of both mainchain and side chain of the substrate. In general, the editing active site ofLeuRS-ED has a very rigid structure with a defined stereochemistry and usesa number of conserved residues to precisely bind and recognize the misactivatedamino acids and discriminate and reject the cognate amino acid, specifically usingMet336, Asp345, and possibly Thr247 for main-chain recognition and Thr252,Met336, and Val338 for side-chain recognition.

在编校反应中错配的氨基酸的水解依赖于对底物主链和支链的适当的结合和正确的识别。ecLeuRS-ED的编校活性位点有一个非常刚性的有很精确设计的立体化学性质的结构，采用一系列保守氨基酸残基来精确结合和识别错配的非共轭氨基酸而区分排斥正确的共轭氨基酸，具体就是采用Met336、Asp345，另外可能还有Thr247对底物主链进行识别，采用Thr252、Met336和Val338对支链进行识别。
