凡纳滨对虾对虾素3a基因的克隆与序列分析
Gene Cloning and Sequence Analysis of Penaeidin 3a in Litopenaeus vannamei
摘要
Abstract
Antibacterial peptide molecules are the main immunity effectors in the innate immunity system of the low invertebrate. They play an important part in preventing pathogens invasion. In order to explore the antibacterial peptides molecular diversity and the molecular structure association, we took Litopenaeus vannamei as the study object. Gene cloning and structure analysis of penaeidin 3a antibacterial peptides gene were done. The results indicated that penaeidin 3a molecular possessed classic shrimp penaeidin domain. And there was a spherical structure that formed by eight conserved cysteine residues. Especial-ly , there was a pro-rich motif which played an important role in forming the special molecular function. This study could provide the theoretical basis for the next functional research of penaeidin molecular.关键词
