Ethanol regulated promoter AOX1

The AOX1 promoter region from Pichia pastoris.

A complex pathway for the metabolism of methanol exists within some species of the Pichia genus. Alcohol oxidase (AO) appears to be the first and major enzyme produced in this metabolic pathway (1). Transcribed from its gene (AOX1), AO converts methanol to formaldehyde within the yeast’s peroxisome (1). A metabolic pathway for the utilization of ethanol is also present within the yeast. However, if both ethanol and methanol is present, the yeast will utilize the ethanol before consuming the methanol (2). Consequently, the AOX gene will not be expressed to produce the AO enzyme until the ethanol has been consumed.
