substrate specificity 中文意思是什麼

substrate specificity 解釋
底物特異性
  • substrate : n. 1. 底層，地層。2. 【無線電】（半導體工藝中的）襯底，基底。3. 【生物學】（生態學中的）基層；【生物化學】受質；被酶作用物。
  • specificity : n. 1. 特異性，特徵；種別性。2. 特效。3. 【化學】專一性。4. 【生物學】專化性。
  1. Protein engineering and site directed mutagenesis have been used to change the active site and alter the substrate specificity of various hydroxynitrile lyases

    研究人員已經利用蛋白質工程和定點突變技術來改變各種醇腈酶的活性位點和底物特異性等。
  2. It was confirmed that the key enzyme of coq10 synthesis is p - hydroxybenzoate polyprenyltransferase, encoded by gene ubia in e. coli and lacks specificity to the aggregation length of its substrate ( polyisoprenyl pyrophosphate ). if gene ubia can be introduced into psb and is high expression in psb, a recombinant strain producing coq10 could be obtained. consequently, the productive cost will decrease sharply

    業已證實coq _ （ 10 ）生物合成的關鍵酶為對羥基苯甲酸聚異戊二烯焦磷酸轉移酶（在大腸桿菌中該酶由ubia基因編碼） ，該類酶對底物聚異戊二烯焦磷酸（ ppp ）的聚合長度並無特殊要求。
  3. Bioassay showed that the second - stage juvenile ( j2 ) could be killed by the raw extract of serine protease. serine protease was characterized after purification with ion exchange chromatography and gel filtration chromatography. the t profile, t stability profile, ph profile, substrate specificity and inhibitor were tested

    該酶分子n -端的氨基酸序列為avidtgveashpef ，通過n -端氨基酸序列設計簡並引物，提取被毛孢owvt - 1的總rna ， rt - pcr克隆了該酶的成熟肽編碼基因（ 1000bp ） ，序列分析表明，絲氨酸含量高達12以上。
  4. No report was found about the metabolism of isoflavone by ugt1a9. the substrates metabolized by ugts encompass a wide range of structurally unrelated substances. previous studies revealed that the individual ugts isozymes tend to exhibit un - strict and overlapping patterns of substrate specificity

    過去的研究認為，葡醛酸綴合反應有各種底物，而且不同的同工酶催化不同結構類型的化合物，但現在認識到ugts與底物的關系不是?一對應的關系，底物譜相互有重疊。
