The Saccharomyces cerevisiae var. uvarum MEL1 gene, conferring production of α-galactosidase, has been cloned to study its expression. Increasing amounts of α-galactosidase protein and activity closely followed the induction of functional MEL1 transcripts (1.65 kb). The initial appearance of the transcript occurred within 3–6 min and the corresponding α-galactosidase activity within 8–10 min of galactose addition. Therefore, regulation of α-galactosidase synthesis operates primarily at the level ...
