How does one protein, araC, act to both promote or repress operon activity? A schematic of the arabinose operon and how the presence of arabinose alters activity of the operon.

L-Arabinose is a naturally occurring isomer that is used in polysaccharides in plants. An inducible arabinose operon codes for a series of transporters and enzymes in important bacterial amounts. This ...

We applied two experiments useful in the study of ligand-regulated DNA binding proteins to AraC, the dimeric regulator of the Escherichia coli L-arabinose operon. In the absence of arabinose, AraC ...

Using the arabinose operon activator AraC, we constructed a system capable of detecting the fungal enzyme scytalone dehydratase (SD) in bacteria, and demonstrated its sensitivity and usefulness in ...

The L-arabinose operon in Escherichia coli is a model system for the study of the control of gene expression. Maximal expression of the araBAD operon requires two positive control components: the araC ...

Reinach, January 20, 2021 - Evolva (SIX:EVE), the Swiss biotech company focused on the research, development and commercialization of products based on nature, launched L-arabinose (previously known ...
