Genetic Sensory Response Unit in Escherichia coli K-12 genome
Gensor Unit Map
Molecular biology levelDetailed: In the absence of trehalose and trehalose-6-phosphate, TreR negatively regulates the expression of genes required for thehalose catabolic process. Under these conditions, TreR remains unmodified, binds its target sites preventing the expression of its regulated genes.Less detailed: In the absence of trehalose and trehalose-6-phosphate, TreR negatively regulates the expression of genes needed for trehalose catabolism.Physiology levelDetailed: The presence of trehalose induces the expression involved with trehalose utilization. Under these conditions the genes necessary for transport and conversion of trehalose-6-phosphate to glucose- 6- phosphate are expressed.Less detailed: The presence of threhalose induces the expression of genes needful for trehalose-6-phosphate transport and conversion to glucose-6-phosphate.
