金屬肽酶 的英文怎麼說
中文拼音 [jīnzhǔtài]
金屬肽酶
英文
metallopeptidase-
The changes of these endopeptidase are different during the former vasing of " samatha " and " belami ". the main eps in petals of " samatha " are the acid thiol - proteinase, metallo - proteinase and the alkali serine proteinase and the main eps in petals of " belami " are the acid thiol - proteinase and serine proteinase. during the later vasing the acid metallo - proteinase and the alkali serine proteinase become main eps in petals of " samatha " and " belami "
這3種內肽酶在兩種切花瓶插初期（盛開以前）的表現不同： 『薩蔓莎』花瓣中以酸性金屬蛋白酶、巰基蛋白酶和堿性絲氨酸蛋白酶起主要作用， 『貝拉米』花瓣以酸性巰基蛋白酶、絲氨酸蛋白酶起主要作用，後期『薩蔓莎』和『貝拉米』花瓣均以酸性金屬蛋白酶、堿性絲氨酸蛋白酶起主要作用。The main study in this paper included as follows : the content and distribution of heavy metals in sediments and benthic organisms from the sewage stream in guangzhou city ; the acute toxicity and joint toxicity of mercury and selenium to swordtail fish ( xiphophorus helleri ) ; the damage of mercury to the indexes of antioxidant system in the gills and livers in swordtail ( including the measurement of the activities of total antioxidative capacity [ t ~ aoc ], superoxide dismutase [ sod ], glutathione peroxidase [ gsh - px ] and the concentration of malondiald - ehyde [ mda ] ) and the relief effects of selenium on it, as well as the physiological damage of mercury on the tissues, namely : the antagonistic effect of na + - k + ~ atpase activity on the tissues between selenite and mercury, and the ultrastructural damage under the exposure of mercury
研究內容主要有：廣州市河涌沉積物及底棲生物體內重金屬含量及評價；汞和硒對劍尾魚的急性毒性和聯合毒性及安全濃度的評價；汞對劍尾魚鰓和肝臟中抗氧化系統的毒性，包括對總抗氧化能力、超氧化物歧化酶、谷胱甘肽過氧化物酶活力及丙二醛含量的測定及硒對其保護作用；汞對劍尾魚組織生理毒性即：汞對na ~ + - k ~ + atpase活力的影響及硒的保護作用和汞和對劍尾魚組織超微結構的損傷等。以高氯酸?硝酸消化法和火焰原子吸收分光光度法測定了廣州市河涌沉積物和底棲生物中重金屬含量。There are at least three kinds of ep in petal : thiol - proteinase, metallo - proteinase, serine proteinase. they gather at the site between 43 kd and 66. 2 kd ( about 52 kd ) on the substrate gel electrophoresis. the optimum ph of thiol - proteinase, metallo - proteinase is ph 6, which are looked as acid ep, the serine proteinase has two forms, one is acid ep ( ph 6 ), and the other is alkali ( ph 10 )
花瓣中都至少有3種內肽酶：巰基蛋白酶、金屬蛋白酶、絲氨酸蛋白酶，三者聚集在底物膠電泳膠條的43kd 66 . 2kd之間的位置，約為52kd ；前兩種最適ph為6 ，是酸性內肽酶，后一種有酸（ ph6 ） 、堿（ ph10 ）兩種存在形式，既是酸性內肽酶又是堿性內肽酶。The cdna sequence with 789 bp encodes an uncompleted open reading frame ( orf ) of 263 amino acids, which included a signal peptide of 18 amino acids, a proposed propeptide of 171 amino acids, a partial mature protein of 74 amino acids. the sequences of signal peptide and propeptide are very similar to ones from wannan agkistrodon acutus reported by fan chunyan, but it only contains partial amino acids of mature protein. the 800 bp is likely to be a part of gene encoding metalloproteinase agkistrodon acutus from guangxi province
結論： 600bp產物和已報道的皖南五步蛇纖溶酶金屬蛋白酶氨基酸序列相比較，有90 . 6 %的同源性； 800bp產物中信號肽及前肽和已報道的皖南五步蛇金屬蛋白酶很相似，同源性為97 . 9 % ，但僅含有部分金屬蛋白酶成熟肽的氨基酸序列，推測此片段為廣< wp = 6 >西五步蛇金屬蛋白酶原基因的一部分。The content of soluble protein is also increased after deficit water stress, but the increasing of " belami " is more significant than that of " samantha ". 5. after deficit water stress, in " samantha ' petals, the metallo - proteinase activities of the optimum ph 6 and the serine proteinase activities of the optimum ph 10 are increased markedly, the thiol - proteinase activities of the optimum ph 6 is decreased markedly
失水脅迫后顯著提高了『薩蔓莎』花瓣中最適ph6條件下金屬蛋白酶、最適月季（ rosahybrde ）切花瓶插期間內肽酶與衰老的關系及失水脅迫對其影響的研究ph條件下的絲氨酸蛋白酶的活性，顯著降低了最適ph6條件下琉基蛋白酶的活性。分享友人
