Background

4-coumarate 3-hydroxylase is an enzyme in the vanillin pathway. 4-coumarate 3-hydroxylase (4-CMH) hydrolyses p-coumaric acid to caffeic acid. It is the 2nd enzyme in the biosynthetic pathway of vanillin bioproduction from the amino acid tyrosine. 4-CMH is biobrick (BBa_K238007) from KULeuven iGEM 2009



Experimental Data

4-CMH under the arabinose promoter (BBa_J23118) were transformed into E.coli 10G cells. An overnight culture of these cells harboring (BBa_I13453)was inoculated into a fresh culture of 5mL minimal media containing tyrsoine. Cells and were harvested for GC-MS after 7 hours of growth.
