The DAL cluster is located in a domain of modified chromatin involving both H2A.Z histone exchange and Hst1-Sum1-mediated histone deacetylation, and it may be a coadapted gene complex formed by epistatic selection.', 'The DAL cluster is the largest metabolic gene cluster in yeast and consists of six adjacent genes encoding proteins that enable Saccharomyces cerevisiae to use allantoin as a nitrogen source. Six of the eight genes involved in allantoin degradation, which were previously scattered around the genome, became relocated to a single subtelomeric site in an ancestor of S. cerevisiae and Saccharomyces castellii.']
