- 摘要:
- 利用生物信息学方法对枸杞MYB103基因编码蛋白的理化性质、亲水性/疏水性、信号肽、跨膜结构域、二级结构、三级结构、结构域和功能分类等方面进行了预测和分析。结果表明：该蛋白属于不具有信号肽的亲水性蛋白，α-螺旋和无规则卷曲是蛋白质二级结构最大量的结构元件，并散布于整个蛋白;且含有2个典型MYB保守结构域，符合R2R3-MYB亚家族保守结构域的特点，这一结果可为植物MYB103的结构与功能及利用研究提供进一步的信息参考。
- Abstract:
- Cloned gene from Lycium barbarum MYB103 was analyzed and predicted by the tools and method of bioinformatics in the following aspects：the composition of amino acid sequence，hydrophobicity or hydrophilicity，signal peptide，transmembrance structure，secondary and tertiary structure of protein，structure domain，function category and so on.The results showed that MYB103 was a hydrophilicity protein without a signal peptide；The main motif of the predicted secondary structure of MYB103 are alpha helix and random coil，beta turn and extended strand are scattered in the whole secondary structure of protein；The MYB103 proteins had two classical MYB conserved domain，its DNA conserved domain was characterized by R2R3-MYB family.The work would be of great information and values for the further structure and function study and utilization of plant MYB103.
