4 . the expressed result of pbv - a , pbv - b and pbv - c showed that the expressed protein was soluble and no inclusion body was been found . sds - page analysis show the molecular weight of protein expressed by phaa was 42kda which was equal to 3 - ketohilase , the molecular weight of protein expressed by phab was 26kda which was equal to acetoacetyl - coa reductase , and the molecular weight of protein expressed by phac was 63kda which was equal to pha synthase
表达载体pbv - a 、 pbv - b和pbv - c经诱导表达，发现所表达的蛋白均为可溶性蛋白，没有包涵体出现；蛋白经sds ? page分析表明，基因phaa表达的蛋白分子量为42kda ，与?酮硫裂解酶分子量大小一致；基因phab表达的蛋白分子量为26kda ，与乙酰乙酰coa还原酶分子量大小一致；基因phac表达的蛋白分子量为63kda ，与pha合成酶分子量大小一致。
