摘要： 摘要：克隆大肠杆菌乙酰辅酶A羧化酶（Acetyl CoA Carboxylase, ACCase）的生物素羧基载体蛋白（biotin carboxyl carrier protein，BCCP）亚基基因accB，构建accB的原核表达载体pGEX-4T-accB，转化大肠杆菌BL21（DE3）工程菌株， IPTG诱导进行融合表达，成功诱导表达了GST-accB融合蛋白，大小为43KDa。

Abstract: Abstract: special primer designed and synthesized based on the sequence of the codon of E.coli, and the gene of accB was obtained by PCR amplification and cloned into prokaryotic expression vector pGEX-4T-1. Then the recombinant expression plasmid pGEX-4T-accB was transformed into E. coli BL21 and the fusion protein of accB was produced by IPTG induction. The analysis of SDS-PAGE showed that the fusion pGEX-4T-accB protein was expressed about 43kD.
