C4H Assay Kit (UV Spectrophotometry)

Cinnamate-4-hydroxylase (C4H) is predominantly found in higher plants, yeast, and fungi. This enzyme catalyzes the hydroxylation of cinnamic acid to produce 4-coumarate and is the second key enzyme in the phenylpropanoid pathway, following L-phenylalanine ammonia-lyase (PAL) .
