The gene encoding a puromycin N-acetyl transferase from Streptomyces alboniger has been cloned next to the SV40 early promoter in a mammalian cells-Escherichia coli shuttle vector. When this construction was introduced into VERO cells it expressed the relevant enzymic activity. Moreover, the puromycin N-acetyl transferase gene has been used as a dominant marker for the selection of transformed mammalian cells able to grow in the presence of the antibiotic.
编码来自白色链霉菌的嘌呤霉素N - 乙酰转移酶的基因已被克隆到哺乳动物细胞 - 大肠杆菌穿梭载体中SV40早期启动子旁边。当将这种构建体导入VERO细胞时,它表达了相关的酶活性。此外,嘌呤霉素N - 乙酰转移酶基因已被用作显性标记,用于选择能够在抗生素存在下生长的转化哺乳动物细胞。
