    • We have discovered DNA binding sites which are specifically recognized by PrtT, a transcriptional activator for protease genes. The DNA binding site can be defined structurally by a consensus nucleotide sequence and functionally by PrtT's ability to regulate transcriptional activation through that sequence. Both PrtT and its cognate DNA binding site (i.e., the nucleotide sequence in each promoter that is recognized by PrtT) can be used in a gene expression system. Possession of only a PrtT transcriptional activator is insufficient, its cognate DNA binding site is necessary for recognition by PrtT (i.e., binding to the site and activating transcription under appropriate conditions). A functional site, such as one obtained from a wild-type fungal gene, will confer PrtT- dependent transcriptional activation on 3'-downstream sequences. A mutation of a wild- type promoter that results in a non-functional site will abolish PrtT-dependent transcriptional activation of 3'-downstream sequences. A mutation of a wild-type promoter that results in a more functional site will enhance PrtT-dependent transcriptional activation of 3'-downstream sequences.
    • 我们已经发现了由蛋白酶基因的转录激活物PrtT特异性识别的DNA结合位点。 DNA结合位点可以通过共有核苷酸序列在结构上定义,并且功能上由PrtT通过该序列调节转录激活的能力。 PrtT及其同源DNA结合位点(即由PrtT识别的每个启动子中的核苷酸序列)均可用于基因表达系统。 只有PrtT转录激活物的拥有不足,其同源DNA结合位点对于PrtT识别(即在适当条件下结合位点并激活转录)是必需的。 诸如从野生型真菌基因获得的功能位点将赋予3'-下游序列上的PrtT依赖性转录激活。 导致非功能位点的野生型启动子的突变将消除3'-下游序列的PrtT依赖性转录激活。 导致更多功能位点的野生型启动子的突变将增强3'-下游序列的PrtT依赖性转录激活。
