Characteristics of galactose transport in Saccharomyces cerevisiae cells and reconstituted lipid vesicles

Abstract

Growth on galactose induces two transport processes, a high-affinity and a low-affinity process. The most important results of a comparison of the two processes were that (i) both depended on GAL2 expression, (ii) only the high-affinity process required galactokinase, (iii) both were down-regulated by catabolite inactivation, (iv) neither was significantly inhibited by carbonyl cyanide-p-trifluoromethoxy-phenyl-hydrazone, (v) neither was differentially inhibited by silver nitrate or mercuric chloride, and (vi) transport activity with a Km closer to that of the low-affinity process of whole cells was reconstituted in fused phospholipid membrane vesicles.
