By NCBI BLASTX server, tomato P56 amino-acid sequence was compared with other pectate and pectin lyases belonging to polysaccharide lyase family Ⅰ 28 proteins ,with higher identity of amino acid sequence compared to P56 amino-acid sequence, were obtained.

利用NCBI BLASTX服务器，搜索与番茄P56蛋白氨基酸序列相似且都属于多糖裂解酶家族Ⅰ的果胶裂解酶蛋白序列共28条，用DNAMAN软件分析其保守区，用CLUSTALX8.0软件进行序列比对和Bi-oEdit软件进行文件转换，进一步用PUAP4.0软件构建系统进化树。

With genomic DNA of Clostridium stercorarium as a template, a structural gene pel9A encoding pectate lyase was obtained by PCR amplification. The pel9A was cloned into pET28a to recombine an express plasmid pPel9A, and then the plasmid pPel9A was transformed into E. coli BL-21, expressed under the control of T7lac promoter at 37℃.

利用PCR技术从耐热梭状芽孢杆菌中扩增得到产耐热果胶裂解酶的结构基因pel9A，并将其克隆于表达载体pET28a中，最后将此重组质粒转化到受体菌E.coli BL-21中进行表达。
