▪ Abstract Helicases are motor proteins that couple the hydrolysis of nucleoside triphosphate
(NTPase) to nucleic acid unwinding. The hexameric helicases have a characteristic ring …

At the end of the multistep transcription process, the elongating RNA polymerase (RNAP) is
dislodged from the DNA template either at specific DNA sequences, called the terminators …

A list of currently identified gene products of Escherichia coli is given, together with a
bibliography that provides pointers to the literature on each gene product. A scheme to …

Rho is the essential RNA helicase that sets the borders between transcription units and
adjusts transcriptional yield to translational needs in bacteria,,. Although Rho was the first …

Transcription factor Rho is a ring-shaped, homohexameric protein that causes transcript
termination through actions on nascent RNAs that are coupled to ATP hydrolysis. The Rho …

In this contribution the use of Analytical Ultracentrifugation (AUC) for the modern analysis of
colloids is reviewed. Since AUC is a fractionation technique, distributions of the …

Rho-dependent transcription terminators participate in sophisticated genetic regulatory
mechanisms, in both bacteria and phages; they occur in regulatory regions preceding the …

Transcription termination factor ρ is a hexameric, RNA-dependent NTPase that can adopt
active closed-ring and inactive open-ring conformations. The Sm-like protein Rof, a homolog …

Escherichia coli protein Rho is required for the factor-dependent transcription termination by
an RNA polymerase and is essential for the viability of the cell. It is a homohexameric protein …

This study investigates the relationship between human erythrocyte glucose transport
protein (GLUT1) oligomeric structure and glucose transporter function. Oligomeric structure …
