the analysis of diploid strains homozygous for the gal3 locus but heterozygous for different combinations of the other mutant galactose loci , which thus have reduced amounts of the gene products of those loci , have demonstrated that , in addition to the two permease units determined in a previous study , a cell requires one complex of the leloir pathway enzymes and two complexes specified by the gal4 locus to be readily induced .
