Two differentially regulated mRNAs with different 5' ends encode secreted with intracellular forms of yeast invertase.

The SUC2 gene of yeast (Saccharomyces) encodes two forms of invertase: a secreted, glycosylated form, the synthesis of which is regulated by glucose repression, and an intracellular, nonglycosylated enzyme that is produced constitutively. The SUC2 gene has been cloned and shown to encode two RNAs (1.8 and 1.9 kb) that differ at their 5' ends. The stable level of the larger RNA is regulated by g...

Comparative studies on the dodecameric and hexameric forms of yeast aminopeptidase I.

Yeast aminopeptidase I, when purified from autolysates of brewer's yeast, is obtained in two molecular froms a) the enzymatically active dodecameric complex (Mr = 640,000, s20,w = 22 S) and b) inactive hexamers (Mr = 320,000, s20,w = 12 S). Although the amino acid composition of the 12 S protein is very similar to that of the active enzyme,the hexamers behave differently in ionic exchange chrom...
