Escherichia coli K-12 substr. MG1655 Polypeptide: BolA DNA-binding transcriptional dual regulator



Gene: bolA Accession Numbers: EG10125 (EcoCyc), b0435, ECK0429

Regulation Summary Diagram: ?

Component of: Grx4-BolA complex (summary available)

Summary:
BolA regulates the transcription of genes involved in the morphology of the cell to confer protection to the cell, specifically under stress conditions and during stationary phase [Santos02, Freire09]. Its overexpression produces round-shaped cells, alters elongation and cell septation [Aldea88, Santos02], induces biofilm formation [Vieira04, Adnan11], impairs cell growth rate [Guinote11], and alters the properties of the outer membrane [Freire06a]. Under poor growth conditions, BolA is essential for normal cell morphology during both the exponential and stationary growth phases and in response to sudden carbon starvation [Santos02].

The transcription expression analysis of some genes with BolA mutants and the presence of a putative helix-turn-helix motif for DNA binding suggest that BolA is a transcriptional regulator, although its regulatory mechanism and specific DNA-binding site remain to be determined [Aldea89]. On the other hand, structural, sequence, and physical interaction analyses show that BolA could be a reductase that interacts with glutaredoxin [Huynen05].

BolA is a member of the BolA family, which is widely distributed among proteobacteria and eukaryotes [Huynen05].

The expression of bolA is regulated at the transcriptional level and at posttranscriptional levels. Its transcription is induced under stationary phase [Lange91] and under different stress conditions, such as carbon starvation, osmotic stress, heat shock, acidic stress, and oxidative stress [Santos99]. On the other hand, bolA mRNA stability during glucose starvation is enhanced in the presence of RNase III function [Freire06].

Subunit of: Grx4-BolA complex

Subunit composition of Grx4-BolA complex = [BolA][GrxD]
         BolA DNA-binding transcriptional dual regulator = BolA (extended summary available)
         glutaredoxin 4 = GrxD (extended summary available)

Summary:
The heterodimeric Grx4-BolA complex can bind an intact [2Fe-2S] cluster and transfer it to the model acceptor protein ferredoxin, although much less efficiently than the Grx4 homodimer [Yeung11].
