✦ Synopsis
To define the extent of intervening sequences required for efficient splicing of the CYH2 gene in Saccharomyces cerevisiae, we have constructed a series of intron mutations. Artificial intron extensions of more than 300 bp of the natural intron lead to an inhibition of splicing whereas intron deletions lead to a drastic improvement of the splicing efficiency. It is shown that deletion of a 32 bp sequence element within the intron is responsible for this drastic improvement.

We have used the special properties of the spo13-1 mutation in order to study the regulation of yeast meiosis by the mating type loci. We have found that both the rme1-1 mutation and the sca mutation allow haploid meiosis in spo13-1 strains. Therefore, haploid meiosis is regulated in the same manner
Clinical manifestations in patients with carbonic anhydrase (CA) I1 deficiency include osteopetrosis, renal tubular acidosis, and cerebral calcification. Of the 39 reported cases of the carbonic anhydrase I1 deficiency syndrome, 72% were patients from North African and Middle Eastern countries, most
In Saccharomyces cerevisiae, the expression of several genes implicated in methionine biosynthesis is co-regulated by a specific negative control. To elucidate the molecular basis of this regulation, we have cloned two of these genes, MET3 and MET25. The sequence of MET25 has already been determined
