by growing in parallel a mutant strain with temperature-sensitive repressor ( glpr ( ts ) ) and an isogenic control with a deletion in the regulator gene at progressively higher temperatures , it was possible to show that the synthesis of aerobic g3p dehydrogenase ( glpd product ) is far more sensitive to specific repression than that of either glycerol kinase ( glpk product ) or g3p transport ( glpt product ) .
