We have sequenced a region containing 32.5 kb of the right arm of chromosome IV of Saccharomyces cerevisiae. Twenty open reading frames (ORFs) greater than 100 amino acids could be identified in this region. Six ORFs correspond to known yeast genes, including DOA4, UBC5 and UBC3, the gene products of which are involved in ubiquitin metabolism. UBC5 is preceded by the two tRNA genes tRNA-Arg2 and tRNA-Asp. Six genes were discovered with homologies to non-yeast genes or with homologies to other yeast ORFs. One of these could be identified as ribosomal protein gene RPS13. The putative function of eight ORFs remains unclear because comparison to different DNA or protein databases revealed no significant patterns. The sequence from cosmid 2F21 was obtained entirely by a combined subcloning and walking primer strategy, and has been deposited in the EMBL data library under Accession Number X84162.

Protein aggregates in motoneurons, a pathological hallmark of amyotrophic lateral sclerosis, have been suggested to play a key pathogenetic role. ALS8, characterized by ER-associated inclusions, is caused by a heterozygous mutation in VAPB, which acts at multiple membrane contact sites between the ER and almost all other organelles. The link between protein aggregation and cellular dysfunction is unclear.

Saccharomyces cerevisiae, a model eukaryotic organism with a rich history in research and industry, has become a pivotal tool for studying Adenosine Deaminase Acting on RNA (ADAR) enzymes despite lacking these enzymes endogenously. This chapter reviews the diverse methodologies harnessed using yeast to elucidate ADAR structure and function, emphasizing its role in advancing our understanding of RNA editing. Initially, Saccharomyces cerevisiae was instrumental in the high-yield purification of ADARs, addressing challenges associated with enzyme stability and activity in other systems.

The major phytochemicals in the roots of Cudrania tricuspidata are prenylated xanthones, exhibiting significant structural diversity and bioactive properties, such as anti-inflammatory, antioxidative, and antitumor effects. The biosynthetic pathways of these compounds have not yet been resolved, limiting their production through synthetic biology. In this study, benzoyl-coenzyme A (CoA) ligase (BZL), benzophenone synthase (BPS), and benzophenone 3'-hydroxylase (B3'H) transcripts involved in the biosynthesis of xanthone were cloned and characterized from C.

Lignin, the most abundant renewable source of aromatic compounds on earth, remains underexploited in traditional biorefining. Fraxetin, a naturally occurring flavonoid, has garnered considerable attention in the scientific community due to its diverse and potent biological activities such as antimicrobial, anticancer, antioxidant, anti-inflammatory, and neurological protective actions. To enhance the green and value-added utilization of lignin, Saccharomyces cerevisiae was engineered as a cell factory to transform lignin derivatives to produce fraxetin.

Competitive fitness is a fundamental concept in evolutionary biology that captures the ability of organisms to survive, reproduce, and compete for resources in their environment. Competitive fitness is typically assessed in the lab by growing two or more competitors together and measuring the frequency of each at multiple time points. Traditional microbial competitive fitness assays are labor intensive and involve plating on solid medium and counting colonies.
