啤酒酵母中编码细胞色素C蛋白1和2的CYC1和CYC7基因,可在不同水平上进行表达。在有氧的情况下,CYP1蛋白与CYC1的UAS1和CYC7的UAS。区相互作用,两种基因方被激活并转录,而且CYC1的转录水平要高于CYC7。本文研究了两个基因中的CYP1结合部位的相同性,发现它们有许多相似之处,但也有差异之处,即在CYC1的两个拷贝的第6位上有CGbp,而在CYC7的同一 The CYC1 and CYC7 genes encoding cytochrome c proteins 1 and 2 in S. cerevisiae can be expressed at different levels. Under aerobic conditions, CYP1 protein interacts with UAS1 and CYC7 UAS of CYC1. The two genes are activated and transcribed, and CYC1 transcripts are higher than CYC7. This study examined the identity of the CYP1 binding sites in the two genes and found that they have many similarities but also differ in that they have CGbp at position 6 of both copies of CYC1 and at the same
