furthermore , the gene product was not expressed when the plasmid was transferred into a strain containing an ino4 mutation , which also prevents expression of chromosomal copies of ino1 . these results establish that the intact structural gene and associated regulatory components have been isolated and that positioning of the gene in its normal chromosomal location is not required for full regulation of inositol-1-phosphate synthase .
