Now , in a study that took more than five years to complete , rockefeller university researchers , in collaboration with a team of bacteriologists at the university of wisconsin , madison , have become the first to solve the structure of a protein complex that protects these cells from singlet oxygen 现在,洛克菲勒大学的研究人员与威斯康星大学的细菌学家一同协作,历经5年多时间的研究,首次获得了一种能够保护细胞免受单态氧损伤的蛋白复合体的晶体结构。
Second , the population genetic structure and genetic diversity of e . mollis were studied by using allozyme eletrophoresis and the electrophoretic data for 6 loci from 3 populations being xiangning , yicheng and pinglu populations in shanxi were got . the level of polymorphism was relatively higher than that of the insect - pollinated outcrossing species ( he = 0 . 375 ) 用等位酶电泳法和biosys - 2软件对山西翅果油树种群的遗传结构和遗传多样性进行了研究,通过对3个种群的6个等位酶位点的电泳分析,结果表明: 5个位点为多态位点, 1个单态位点。
The stations e2 and 1 - 4 were located at the cold water mass area of the central yellow sea , which characterized by low temperature , high salinity and stable theromocline would generate a retention mechanism that promoted the formation of separate , self - supporting stocks of krill . 2 genetic diversity and differentiation of p . latifrons specimens of p . latifrons were collected from the east china sea and the south china sea . the zymogram phenotypes of aspartate aminotransferase ( e . c . 2 . 6 . 1 . 1 , aat ) , alkaline phosphatase ( e . c . 3 . 1 . 3 . 1 , alp ) , a - amylase ( a - amy ) , r - amylase ( r - amy ) , esterase ( est ) , lactate dehydrogenase ( ldh ) , raalate dehydrogenase ( mdh ) , malic enzyme ( me ) , and phosphoglweoisomerase ( pgi ) were scored (二)宽额假磷虾遗传多样性和遗传分化研究1 .本文对东海外海和南海2个站位宽额假磷虾群体进行了分析,在检测的9个酶系统中,共检测到11个酶位点:天冬氨酸转氨酶( l个位点, 2个等位基因) ,碱性磷酸酶( 2个位点, a加了和a加2各有2个等位基因) , r淀粉酶( l个位点, 2个等位基因) ,醋酶( 2个位点, es巧和est7各有2个等位基因) ,苹果酸脱氢酶( l个位点, 3个等位基因) ,苹果酸酶( l个位点, 2个等位基因) ,乳酸脱氢酶( l个位点, 4个等位基因) ,磷酸葡萄糖转氨酶( l个位点, 3个等位基因) ; a淀粉酶为单态。
