摘要
自溶现象广泛存在于各种微生物中,但有关食药用菌虎奶菇(Pleurotustuber-regium(Fr.)Sing)菌丝体自溶的研究国内外均未见报道。本文通过筛选获得引起自溶的较佳条件,用该条件进行虎奶菇自溶处理,最终应用差异蛋白质组分析方法研究其自溶。
     首先利用液体发酵法培养虎奶菇菌丝体,分别研究了不同温度、pH值与渗透压等因素对其菌丝体自溶的影响。结果表明,虎奶菇菌丝体较佳的单因素自溶条件分别为温度40℃、pH 9.0、NaCl浓度3-4%。
     然后比较了虎奶菇菌丝体蛋白质的三种提取方法以寻找一种适用于蛋白质组学双向电泳的高分辨率的提取方法。结果表明TCA/丙酮法提取所得到的蛋白质样品的双向电泳图谱效果最佳。同时获得制备胞外蛋白样品的方法。
     最终以40℃处理为实验组,10℃处理为对照组,采用差异蛋白质组学方法研究虎奶菇的自溶现象,得到22个明显上调的蛋白质点,经MALDI-TOF/MS检测及肽指纹图谱(PMF)分析,其中8个蛋白质得到鉴定,表现为:蛋白酶体参与泛素-蛋白酶体通路,β-1,3-glucanosyltransferase及微管蛋白与细胞壁的更新、细胞壁的修补相关,蛋白酶和内切葡聚糖酶促进细胞壁和细胞质自然降解,14-3-3蛋白参与细胞信号转导。因此推测菌丝体自溶过程如下:当营养条件缺乏或高温下,往往出现细胞正常代谢失控,细胞内部结构解体,这时蛋白酶体承担了降解细胞内蛋白质的任务,蛋白酶和内切葡聚糖酶等水解酶的大量释放促进细胞壁和细胞质降解,获得的自溶产物为其后代生长提供营养源;大量合成β-1,3-glucanosyltransferase及微管蛋白等,参与细胞壁的更新、修补,以维持其正常形态和功能。
Autolysis phenomena exist widely in a variety of microbes.However,the mycelium autolysis of the edible and medical Pleurotus tuber-regium(Fr.) has not been reported at home and abroad.This experiment initiated from screening the appropriate conditions of Pleurotus tuber-regium(Fr.) mycelium autolysis,then treating the mycelium with the optimal autolysis condition,and finally analyzing the autolysis by using differential proteomic method.
     First,the effects of different temperature,pH and osmotic pressure on mycelium autolysis were studied via liquid fermentation of Pleurotus tuber-regium(Fr.) mycelium.The results showed that the appropriate monofactorial condition of autolysis is temperature 40℃,pH 9.0 and NaCl concentration 3-4%.
     Then,an efficient method for extracting the total proteins from the Pleurotus tuber-regium(Fr.) mycelium was established with high resolution applicable to the proteomic 2-D electrophoresis analysis.The results indicated that the TCA/acetone method was optimal for extracting total protein for 2-D electrophoresis.The method of extracting extracellular protein was also obtained in this research.
     Lastly,the autolysis of Pleurotus tuber-regium(Fr.) mycelium was investigated by differential proteomics,using 40℃treatment as experimental group and 10℃as control.Twenty-two protein spots with remarkable up-regulation were obtained for analysis by MALDI-TOF/MS and PMF,and eight proteins were identified.Of these proteins,proteasome participates in ubiquitin-proteasome pathway;β-1,3-glucanosyltransferase and tubulin are involved in the renew and repair of cell wall;protease and endo-glucanase promote the natural degradation of cell wall and cytoplasm;and 14-3-3 protein deals with cell signal transduction.Thus,the process of Pleurotus tuber-regium(Fr.) mycelium autolysis is presumed as follows:under nutrition shortage or high temperature treatment,the cells undergo metabolic malfunction and inner structure disruption;then the proteasome degrades the intracellular proteins and leads to the release of hydrolases such as prolease and endo-glucanase to accelerate cell wall and cytoplasm degradation;the autolysis products serve as the nutrition for the progeny;and theβ-1,3-glucanosyltransferase and tubulin maintain the normal cell shape and function by renewing and repairing cell wall.
