摘　　要：为深入了解希金斯炭疽菌中化合物酶类蛋白(CAZymes)的功能,以前期获得的238个CAZymes为研究对象,对其进行理化性质预测分析,结果表明,近2/3的蛋白理论等电点小于6,属于酸性蛋白,同时,通过随机数软件对上述蛋白进行10%抽样分析,明确了不同理论等电点类别的分泌蛋白所具有的分子质量、分子式、半衰期、不稳定性系数、脂肪族氨基酸指数、总平均亲水性等理化性质。To identify the function of CAZymes proteins in Colletotrichum higginsianum,the physical and chemical properties were analyzed based on the 238 CAZymes proteins sequence.The results showed that the protein isoelectric point was less than 6 in nearly two-thirds proteins,belonging to acidic protein.Ten percent of the sample proteins were then screened by the random number software,to define the molecular mass,the molecular formula,half-life,the instability factor,aliphatic amino acid index,and total average hydrophilicity properties of secreted protein from different theoretical isoelectric point category.
