Besides , no distinct difference of the response between 60co y - ray irradiation and electron beam irradiation is found , nor energy and dose rate reliability 此外，在本实验范围内未发现丙氨酸薄膜剂量计对射线和电子束的响应存在明显的差异，同时未发现明显的能量和剂量率依赖性。
Acbf is a transcription factor that combined with the ac - rich region of the promoter region . it has been cloned at arabidopsis thaliana , nicotiana tabacum and so on Acbf编码了结合在苯丙氨酸解氨酶启动子ac富集区上的一个转录因子， acbf基因已经在拟南芥、烟草等植物中得到了克隆。
Most proteins have amino acids with aromatic ring , so they have yellow reaction . phenylalanine is not easy to nitrify , so it is necessary to add in a little vitriol oil 多数蛋白质分子含有带苯环的氨基酸，所以都会发生黄色反应。苯丙氨酸不易硝化，需加少量浓硫酸后才能够发生黄色反应。
Compared with the common cultivation , the contents of carotenoid , phenylalanine , products of browing reaction and neophytadiene were greatly increased in every treatment 并使烟叶中性致香物质总量增加，类胡萝卜素类、苯丙氨酸类、棕色化产物、新植二烯等致香物质含量均较对照有很大提高。
It was found that the levels of catechins and proanthocyanins in those subclones accumulating anthocyanins were also raised , and were independent of the activity of phenylalanine ammonia - lyase 发现积累色素的细胞系中，儿茶素与原花色素的形成能力也得到了大幅度提高，且与苯丙氨酸解氨酶活性无关。
In microorganisms and plants the first step in the aromatic acid biosynthetic pathway is the condensation of pep and e4p , with the release of the phosphate of pep and the formation of dahp 在细菌和植物中，由公共途径莽草酸途径以及三个专一性途径分别合成苯丙氨酸、酪氨酸和色氨酸三种芳香族氨基酸。
The effects of six effectors , polyethylene glycol ( peg ) 6000 , d - sorbitol , trehalose , dithiothreitol , glycerol and glutarie dialdehyd on pal activity in enzymatic reaction were investigated in this article 摘要实验考察了聚乙二醇6000 、 d -山梨醇、海藻糖、二巯基苏糖醇、甘油、戊二醛对酶反应中苯丙氨酸解氨酶活力的影响。

Chorismate acid is branch point in aromatic amino acids biosynthesis , related to phenylalanine , bifunctional enzymes chorismate mutase / prephenate dehydratase ( encoded by phea ) is rate - limiting enzyme 分支酸是芳香族氨基酸合成途径的分支点，与苯丙氨酸合成有关，双功能酶分支酸变位酶-预苯酸脱水酶( phea基因编码)是关键酶。
