Protein family
In molecular biology, the BolA-like protein family consists of the morpho-protein BolA from Escherichia coli , the Fra2 protein from Saccharomyces cerevisiae , and various homologs . The BolA protein is a DNA-binding regulator;[ 1] the Fra2 protein is an iron sulfur cluster protein that binds Grx3/4 and is involved in regulating iron levels
.[ 2]
In E. coli , over-expression of this protein causes round morphology and may be involved in switching the cell between elongation and septation systems during cell division .[ 3] The expression of BolA is growth rate regulated and is induced during the transition into the stationary phase .[ 3] BolA is also induced by stress during early stages of growth [ 3] and may have a general role in stress response . It has also been suggested that BolA can induce the transcription of penicillin binding proteins 6 and 5.[ 3] [ 4]
