A genomic survey of nitrogen assimilation pathways in budding yeasts (sub ‐phylum Saccharomycotina).

This study also successfully identified yeast homologs of all six previously known eukaryotic genes involved in the biosynthesis of the molybdenum cofactor (MoCo), which is required for the activity of the nitrogen assimilation‐associated enzymes nitrate reductase and xanthine oxidoreductase. Anal ysis of 1187 upstream intergenic regions identified three novel putative regulatory motifs for the assimilation of uracil, purines and uric acid as well as a possible role for the MADS‐box transcription factor Mcm1 in the regulation of amine assimilation genes.
