rbcR [rcbR的校正]是一种编码转录调节因子LysR家族成员的基因,位于光合细菌嗜硫小红卵菌中1,5-二磷酸核酮糖羧化酶/加氧酶基因表达集的上游。

rbcR [correction of rcbR], a gene coding for a member of the LysR family of transcriptional regulators, is located upstream of the expressed set of ribulose 1,5-bisphosphate carboxylase/oxygenase genes in the photosynthetic bacterium Chromatium vinosum.

Abstract

An open reading frame, rbcR, was identified 226 bp upstream of rbcAB, i.e., the ribulose 1,5-bisphosphate carboxylase genes expressed in the phototrophic purple bacterium Chromatium vinosum. Several features reveal that rbcR encodes a member of the LysR family of transcriptional regulators, in which an anomalous content of lysine and arginine residues (Lys/Arg anomaly) was found. The expression of rbcR in Escherichia coli as a protein fused to the N-terminal region of beta-galactosidase led to reduced expression of rbcAB. Thus, rbcR is likely to encode a trans-acting transcriptional regulator of rbcAB expression in C. vinosum.

摘要

在光合紫色细菌嗜硫小红卵菌(Chromatium vinosum)中表达的1,5-二磷酸核酮糖羧化酶基因rbcAB上游226 bp处鉴定出一个开放阅读框rbcR。若干特征表明rbcR编码转录调节因子LysR家族的一个成员,其中发现赖氨酸和精氨酸残基含量异常(赖氨酸/精氨酸异常)。rbcR在大肠杆菌中作为与β-半乳糖苷酶N端区域融合的蛋白表达,导致rbcAB表达降低。因此,rbcR可能编码嗜硫小红卵菌中rbcAB表达的反式作用转录调节因子。
