catalytic center meaning in English
催化中心
Examples
- The deduced 3 amino acid residues , d32 , h64 , and s221 , were identical with 3 essential amino acids in the catalytic center of protease
成熟蛋白酶全长275个氨基酸残基，其中， d32 ， h64 ，和52213个氨基酸残基为催化活性中心。 - The metal ion may be the catalytic center of the cofactor , or it may serve to bind the enzyme and substrate together to hold the enzyme in a catalytically active conformation
金属离子可以是辅助因素的催化中心，也可以帮助形成酶活性所必须的构象。 - The catalytic center of an enzyme is composed of a set of amino acids whose three - dimensional arrangement forms the “ active - site ” that allows them to efficiently bind and modify the substrate
酶的催化中心是由一组氨基酸组成，其三维结构形成活性位点，允许它高效地结合或修饰底物。 - In the procedure , carbon nanotubes were oxidized by nitric acid and then neutralized with naoh to create carboxyl surface groups which were used to adsorb ni ( superscript 2 + ) ions , thereafter the adsorbed ni ( superscript 2 + ) ions were chemically reduced into ni nano - particles as a catalytic center for electroless nickel deposition , all these were further confirmed by infrared absorption spectra and electron microscopic observations
碳纳米管经硝酸氧化和碱中和后表面生成羧基，利用羧基吸附镍离子，之后吸附的镍离子被化学还原为镍的纳米微粒并成为化学镀镍的催化活性中心。 - Dna sequence analysis showed that the cloned nk gene was highly homologous to the sequence reported by nakamura . the deduced amino acid sequence also had the conserved sequences ( serine 221 , histidine 64 , and aspartic acid 32 ) which was essential for the catalytic center of serine proteases . the nk gene was then cloned into the transfer vector pvl1393
本实验以b . subtilis ( natto )基因组dna为模板扩增了nk基因，测序结果显示与nakamura报道的纳豆激酶基因高度同源，其氨基酸序列也含有丝氨酸蛋白酶的活性保守中心( serine221 ， histidine64 ， asparticacid32 ) 。
