2.5.1.93	additional information	blue light effectively represses the PHB geranyltransferase activity	2	
2.5.1.93	additional information	compounds showing strong competition/inhibition are simple phenols having phenolic OH residues, while carboxylic acid does not seem to influence the enzyme activity. Phenylpropanoid gives no apparent inhibition. No or poor inhibition by benzoate, 2-hydroxybenzoate, 3-hydroxybenzoate, ferulic acid, and 4-coumaric acid	2
