ABSTRACT Wild-type strains of Escherichia coli are unable to utilize aromatic β-glucosides such as arbutin and salicin because the major genetic system that encodes the functions for their catabolism, the bgl operon, is silent and uninducible. We show that strains that carry an activated bgl operon exhibit a growth advantage over the wild type in stationary phase in the presence of the rpoS819 allele that causes attenuated rpoS regulon expression. Our results indicate a possible evolutionary advantage in retaining the silent bgl operon by wild-type bacteria.

Abstract A new mutation, bglJ4, has been characterized that results in the expression of the silent bgl operon. The bgl operon encodes proteins necessary for the transport and utilization of the aromatic β-glucosides arbutin and salicin. A variety of mutations activate the operon and result in a Bgl+ phenotype. Activating mutations are located upstream of the bgl promoter and in genes located elsewhere on the chromosome. Mutations outside of the bgl operon occur in the genes encoding DNA gyrase and in the gene encoding the nucleoid associated protein H-NS. The mutation described here, bglJ4, h

ABSTRACT The Escherichia coli bgl operon is of interest, since its expression is silent (phenotypically Bgl−), at least under standard laboratory conditions. Here we attempted to identify atrans-acting factor(s) that is presumably relevant to the regulation of bgl by a random insertion mutagenesis with mini-Tn10. These collected mutations, conferring the phenotype of Bgl+, were localized in three loci on the genetic map, two of which appeared to be hns andbglJ, which were previously implicated as the factors affecting the Bgl phenotype. The other locus at 1 to 2 min on the genetic map appeared

ABSTRACT The bgl promoter is silent in wild-type Escherichia coli under standard laboratory conditions, and as a result, cells exhibit a β-glucoside-negative (Bgl−) phenotype. Silencing is brought about by negative elements that flank the promoter and include DNA structural elements and sequences that interact with the nucleoid-associated protein H-NS. Mutations that confer a Bgl+ phenotype arise spontaneously at a detectable frequency. Transposition of DNA insertion elements within the regulatory locus, bglR, constitutes the major class of activating mutations identified in laboratory culture

ABSTRACT From evolutionary and physiological viewpoints, theEscherichia coli bgl operon is intriguing because its expression is silent (Bgl− phenotype), at least under several laboratory conditions. H-NS, a nucleoid protein, is known as a DNA-binding protein involved in bgl silencing. However, we previously found that bgl expression is still silent in a certain subset of hns mutations, each of which results in a defect in its DNA-binding ability. Based on this fact, we proposed a model in which a postulated DNA-binding protein(s) has an adapter function by interacting with both the cis-acting

Streszczenie:

Cryptic genes are phenotypically silent DNA sequences with the potential to code for a function, but remain inactive during the normal life span of the organism. However they can be activated by a single mutational event such as recombination, deletion, insertions or point mutation, resulting in a discernible phenotype. The bgl operon of E. coli, involved in the uptake and breakdown of plant derived aromatic -glucosides salicin and arbutin, is one of the well studied examples of cryptic genetic systems. The present study was aimed at understanding the causes for the conservation of the silent
