As KlGal1p plays a dual role, as both inducer and galactokinase, our analysis indicates that only 10% of total KlGal1p translocates into the nucleus to act as inducer, ... used a steady- state modeling approach to quan- tify the underlying molecular mechanism for the GAL system of K. lactis and to obtain a systems’ level understanding of its behavior. The steady- state ... GAL system of K. lactis was validated experi- mentally by obtaining steady- state protein expression levels in a wild-type strain and in a mutant strain lack- ing gene KlGAL80. The steady- state...
