E. coli histone-like protein HU has been shown to interact with different topological forms of DNA. Using radiolabeled HU, we examine the effects of DNA supercoiling on HU–DNA interactions. We show that HU binds preferentially to negatively superco

Transcription by RNA polymerase can stimulate localized DNA supercoiling in Escherichia coli . In vivo , there is extensive experimental support for a “twin-domain” model in which positive DNA supercoils are generated ahead of a translocating RNA

The first discovery of an Hsp70 chaperone gene was the isolation of an Escherichia coli mutant, dnaK756, which rendered the cells resistant to lytic infection with bacteriophage lambda. The DnaK756 mutant protein has since been used to establish many

We have used a set of bacteriophage lambda and Escherichia coli replication proteins to establish rolling circle DNA replication in vitro to permit characterization of the functional properties of lambda replication forks. We demonstrate that the lam

Central to the chaperone function of Hsp70 stress proteins including Escherichia coli DnaK is the ability of Hsp70 to bind unfolded protein substrates in an ATP-dependent manner. Mg2+/ATP dissociates bound substrates and, furthermore, substrate bindi

Transcription of closed circular DNA templates in the presence of DNA gyrase is known to stimulate negative DNA supercoiling both in vivo and in vitro. It has proven elusive, however, to establish a general system in vitro that supports transcription

It has previously been established that sequences at the C termini of polypeptide substrates are critical for efficient hydrolysis by the ClpP/ClpX ATP-dependent protease. We report for the bacteriophage lambda O replication protein, however, that N-
