Serah W Kimani et al.
The amidase from Geobacillus pallidus RAPc8, a moderate thermophile, is a member of the nitrilase superfamily and catalyzes the conversion of amides to the corresponding carboxylic acids and ammonia. It shows both amide-hydrolysis and acyl-...
Structure of the nondiscriminating aspartyl-tRNA synthetase from the crenarchaeon Sulfolobus tokodaii strain 7 reveals the recognition mechanism for two different tRNA anticodons [0.03%]
来自栖热菌株7的非识别天冬氨酸氨酰-TRNA合成酶结构揭示了两种不同反密码子的识别机制
Yoshiteru Sato,Yohei Maeda,Satoru Shimizu et al.
Yoshiteru Sato et al.
In protein synthesis, 20 types of aminoacyl-tRNA synthetase (aaRS) are generally required in order to distinguish between the 20 types of amino acid so that each achieves strict recognition of the cognate amino acid and the cognate tRNA. In...
Structure-factor extrapolation using the scalar approximation: theory, applications and limitations [0.03%]
标量近似结构因子外推:理论、应用及局限性
