Abstract
The expression of sll1689, an open reading frame from the cyanobacterium Synechocystis sp. strain PCC 6803 putatively encoding a member of the sigma(70) family of sigma factors, appears to be regulated by the nitrogen control transcription factor NtcA. Disruption of sll1689 had no noticeable effect on exponential growth, identifying its product as a member of the group 2, nonessential class of sigma(70)-like sigma factors; however, this disruption decreased the viability of the cells after long periods of nitrogen starvation. We have named this gene rpoD2-V. The expression of glnN, encoding a type III glutamine synthetase, was impaired in strains bearing an inactivated copy of the rpoD2-V gene.
摘要
集胞藻6803（Synechocystis sp. strain PCC 6803）的一个开放阅读框sll1689，推测其编码σ因子σ⁷⁰家族的一个成员，该基因的表达似乎受氮控制转录因子NtcA调控。sll1689的缺失对指数生长期生长没有明显影响，表明其产物属于第2组非必需类σ⁷⁰样σ因子；然而，这种缺失会降低细胞在长期氮饥饿后的活力。我们将该基因命名为rpoD2-V。编码III型谷氨酰胺合成酶的glnN在携带rpoD2-V基因失活拷贝的菌株中表达受损。
