The YlALK1 gene, which encodes cytochrome P450ALK1, plays a primary role in the assimilation of n-decane by yeast Yarrowia lipolytica and is inducible by n-decane at the transcriptional level. Deletion analysis of the YlALK1 promoter revealed that a 95-bp region on the YlALK1 promoter (from the position -400 to -304 upstream of the ATG codon) is essential for the induction by n-decane and we named this region ARRI (alkane-responsive region). ARRI was found to be made up of two different elements, ARE1 (alkane-responsive element 1; from -394 to -371) and ARE2 (from -325 to -305). By electrophoretic mobility shift assay, we found that the respective elements gave specific shift bands with the extracts from Y. lipolytica cells grown on n-alkane, but not much evidently from the cells grown on glycerol or glucose. This suggests that proteins that specifically bind to these elements are present and their binding or synthesis is dependent on n-alkane. (C) 2002 Elsevier Science (USA). All rights reserved.
