Abstract

The present invention provides modified promoters from Candida troplicalis CYP and POX4 genes. The modified promoters have various sequence motifs added, deleted, or altered in order to modulate expression of a coding sequence operably linked thereto. The sequence motifs comprise repressors of gene induction (URS sequences) and activators of gene induction (UAS sequences) as well as oleic acid response elements (ORE sequences). Yeast host cells comprising such modified promoters are also provided. Methods of altering expression of a protein of the beta or omega oxidation pathways using a subject modified promoter are also provided.

Claims (2)

1. A modified Candida tropicalis cytochrome p450 (CYP) CYP52A2A gene promoter having the nucleic acid sequence of SEQ. ID. No. 91 wherein an Upstream Regulatory Sequence-1-like (URS1-like) sequence which consists of SEQ. ID. No. 22 is deleted and wherein activity of said gene promoter is inactivated.

2. An isolated yeast host cell transformed with the modified gene promoter of claim 1 .
