Gensor Unit       
Name: MhpR
Description: Molecular biology level
Detailed: In the presence of aromatic compounds, MhpR positively regulates the expression of genes required for phenylpropanoid catabolic process. Under this condition, MhpR is modified to MhpR-3-(3-hydroxyphenyl) propionate, binds its target sites enabling the expression of its regulated genes.
Less detailed: In the presence of aromatic compounds, such as 3-(3-hydroxyphenyl)propionate, MhpR positively regulates the expression of genes needed for phenylpropanoid catabolic process.

Physiology level
Detailed: The presence of 3-(3-hydroxyphenyl)propionate induces the expression of genes involved with assimilation of aromatic compounds. Under this condition the genes necessary for conversion of 3-(3-hydroxyphenyl)propionate to acetaldehyde are expressed (or induced).
Less detailed: The presence of 3-(3-hydroxyphenyl)propionate induces the expression of genes needful for the conversion of aromatic compounds to acetaldehyde as precursor of acetyl-CoA.
