Quorum - sensing systems can be divided into two paradigmatic classes : luxi / luxr - type quorum - sensing systems in gram - negative bacteria which produce acyl - homoserine lactone ( ahl ) autoinducers, and oligopeptide / two - component - type quorum - sensing ciruits in gram - positive bacteria which produce autoinducing peptide ( aip ) autoinducers. in contrast to the two paradigmatic quorum - sensing systems, vibrio harveyi produces and responds to an ahl - type autoinducer termed ai - 1 and a novel signal molecule named ai - 2
Qs系統可分為兩種典型的類型，即革蘭氏陰性細菌的luxi luxr型qs系統，革蘭氏陽性細菌的寡肽雙組分型qs系統，分別以酰基高絲氨酸內酯（ acyl - homoserinelactones ， ahl ） 、寡肽（ autoinducingpeptide ， aip ）為信號分子。The results showed that high concentration of 2, 4 - d was required for callus induction from mature seeds of tall fescue, and combination of 8mg / l 2, 4 - d with 2mg / l aba gave best induction effects. by slicing sterilized seeds longitudinally or cutting embryos, callus induction frequency was profoundly increased over intact seeds from one and half to eight times. adoption of ms basal medium and supplementation of 0. 5g / l casamino acids and 0. 5g / l glutamine in medium were found to help to facilitate callus induction
研究表明，高羊茅成熟種子愈傷組織誘導需要較高濃度的2 ， 4 - d ，以8mg l2 ， 4 - d與2mg laba配合能獲得最佳的誘導效果；種子滅菌后縱切或切胚，可使出愈率成倍提高；採用ms基本培養基和在培養基中添加0 . 5g l的水解酪蛋白與谷氨酰胺也有助於提高出愈率；低劑量（ 10gy ）射線輻照處理對成熟種子愈傷組織尤其是胚性愈傷組織形成有一定的刺激效應。L - glutamine is a non - essential, neutral, genetically coded amino acid. occurring widely in plant and animal tissue and produced commercially for use in medicine and biochemical research
谷酰胺是一種非必需的中性氨基酸，大量的含于動植物組織，大量生產用於醫藥和生化研究。The results showed that the open reading frame of chil - 15 cdna encompassed 564 base pairs ( bp ) and encoded a protein of 187 amino acids with three potential n - linked glycosylation sites, four conserved cysteine residues, two out - of - frame atg initiation codons in the 5 " untranslated region, and a signal peptide consisting of 66 amino acids. when it was compared with the published sequence of chil - 15 cdna, 7 mutant sites were found, and 5 amino acids were changed in predicted amino acids, which indicated that chil - 15 may be polymorphic
結果顯示，本研究所用白來航雞il - 15cdna5 』非編碼區有兩個框外atg起始密碼子，開放閱讀框由564bp組成，編碼187個氨基酸，其中n末端信號肽含有66個氨基酸殘基，在第48 、 149和166位的天冬酰胺殘基上有三個潛在的n -糖基化位點。Oligochitosan is not only water - soluble, non - toxic, biocompatible but also possesses versatile functional properties of chitin and its derivatives, such as polyelectrolite properties, the presence of reactive functional groups, gel - forming ability, high adsorption capacity, bacteriostatic, fungistatic and antitumour influence, and thus it has attracted more and more attention in the field of biology. previous investigations have shown that chitin and its derivatives have immunoenhancement activities
殼寡糖是由3 10個n -乙酰氨基葡萄糖殘基或氨基葡萄糖殘基通過- 1 ， 4 -糖苷鍵連接而成的寡糖，它具有良好的水溶性、組織兼容性，在生物體內易降解，同時也具有抑菌、抗腫瘤、調血脂、調節免疫及活化腸道雙歧桿菌等多種生理功能，因此已成為眾多領域的研究熱點。Methods : in the present experiment, acid dehydroxy amino acid analysis and isoelectric focusing in polyacylamide gels were used and the amino acid composition and isoelectric point of porcine platelet - derived growth factor were studied
方法：用酸水解及聚丙烯酰胺凝膠等電聚焦的方法測定豬血小板衍生生長因子的氨基酸含量、組成成分和等電點。" on a 100 millimeter [ total possible ] pain score, the ibuprofen group dropped by about 24 millimeters on average, the acetaminophen group 12 millimeters and the codeine group 11 millimeters, " clark said
「如以100毫米（可能達到的最高值）作為疼痛評價分值的話，布洛芬組平均降低24毫米，對乙酰氨基酚組和可待因組分別降低12毫米和11毫米。 」克拉克說道。Acetylornithine deacetylase is the key enzyme of producting l - methionine. we mainly do research work on the construction of acetylornithine deacetylase gene - engineering strain and characteristic of proteinase. in order to get high expression deacetylase strain, we obtain the gene by pcr arge gene. the product ( 2800bp ) was cloned into puc19 plasmid and confirmed with blue / white dot screening > restriction enzyme analysis and pcr. then taking the nucleotide sequencing compared with the sequence at blast of u. s. a. we constructed a high expression of gene - engineering strain - pxj 128 which containing the arge gene on the high expressing system of pxji18 with activity of acetylornithine deacetylase above 20000u / g
為了獲得高效表達的脫乙酰鳥氨酸酶工程菌株，在工程菌技術改造及其固定化研究做了進一步的研究和探討。我們採用基因工程技術，通過pcr技術擴增出了酰化酶關鍵酶基因?脫乙酰鳥氨酸酶基因arge ，將其克隆到puc19載體中，經酶切鑒定、 pcr鑒定篩選出重組陽性質粒，並測序鑒定，通過美國blast程序進行了基因數據庫相似性比較分析。Apain score below 30 millimeters is considered adequate relief, clarksaid. " about 50 percent of the ibuprofen group got there, but only 36percent of the acetaminophen group vs. only 40 percent of the codeinegroup.
