The 5＇coding region of its eDNA was optimized according to the codon bias of Pichia pastoris to make it secretively express in Pichia pastoris with higher performance. Two-step DNA synthsis was used to synthesize the eDNA sequence being optimized of ADTZ. OPT-ADTZ was connected with constitutive plasmid pGAPZaA to construct the reecombinant plasmid pNOA. pNOA was linearized and then transformed into Pichia pastoris GS115. Then codonoptimized ADTZ was constitutively and secretively expressed in Pichia pastoris.

Traditional ways of demarcation tends to focus on revelation of the characteristics of essential facilities that have proved far from satisfactory,among which,the criterion laid down by the court in the case of MCI seems tautological in logic;the public welfare criterion appears to transfer a vague issue into an even indefinite one;while the competitor standard ignores the integral effectiveness of the whole market;...

其中，美国"MCI"案中法院提出的标准存在逻辑上的同语反复；公共利益标准将有待澄清的问题转化为了另一个不确定的问题；竞争者标准忽略了市场的整体效果；消费者偏好标准只是对于特定情况的处理，不能成为一个基本的判断标准。核心设施界定的关键是对"不可复制性"的理解，通过借鉴相关市场界定的方法，可以确定替代发生的范围，以及替代实现的程度，从而对正确地适用核心设施理论提供新的思路。
