gram molecule 中文意思是什麼
gram molecule
解釋
【化學】克分子。-
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。 -
In aqueous solution, interaction between crude venom and different bacteria including gram - positive bacteria, i. e. streptococcus mutans, streptococcus aureus, and gram - negative bacteria, i. e. e. colik12, was investigated in detail. molecule weights of multiple proteins were identified as 110kda, 47kda, 24kda, 23kda and 15kda by sds - page, respectively. it had little influence on extraction of snake venom proteins by the same cells of streptococcus mutans even used for 10 cycles
其次，在利用s . mutans分離細菌特異性抗體的基礎上，首次利用細菌篩選作用蛋白，將革蘭氏陽性菌（ s . mutans和s . aureus ）和革蘭氏陰性菌（ e . colik12 ）分別與蘄蛇蛇毒相互作用，發現有五種蛇毒蛋白能夠與細菌相互作用，其分子量分別為110kda 、 47kda 、 24kda 、 23kda和15kda ；同時表明s . mutans菌體能夠多次與蛇毒相互作用，並且對作用蛋白的結合沒有影響。 -
Three kinds of works were described in this thesis with bacillus thuringiensis as major material. 1. autoinducer inactivity protein aii in b. thuringiensis strains and its effect on pathogenicity of plant - pathogen bacteria autoinducer, especially ahl molecule, is a kind of cell - to - cell communication molecule that has extensive distribution in gram - negative plant pathogen bacteria
蘇雲金芽胞桿菌自身誘導物抑制蛋白aii及其對植物病原菌致病性的影響自身誘導物（ autoinducer ，以下簡稱ai ）分子是一種廣泛存在於革蘭氏陰性植物病原菌的細胞間信號分子，與病原菌的致病性有著直接或問接的關系。
