4-hydroxy phenylacetate 3-monooxygenase reductase component B (S. cerevisiae), HpaB

This part encodes 4-hydroxy phenylacetate 3-monooxygenase reductase component B from Lysinibacillus capsici

Biology

The organism this gene is initially expressed in is L. capsici.

HpaB is a reduced FAD (FADH2)-utilizing monooxygenase. This enzyme component uses FADH2 and O2 to oxidize 4-hydroxyphenylacetate [1].

Usage

This enzyme is implemented in the synthesis pathway to produce rosmarinic acid in the Saccharomyces cerevisiae culture. HpaB is part of the two-step process of converting p-coumaric acid into caffeic acid, which adds a hydroxyl group onto the phenyl ring.
