Evolutionary Diversification of Alanine Transaminases in Yeast: Catabolic Specialization and Biosynthetic Redundancy
Gene duplication is one of the major evolutionary mechanisms providing raw material for the generation of genes with new or modified functions. The yeast Saccharomyces cerevisiae originated after an allopolyploidization event, which involved mating between two different ancestral yeast species. ScALT1 and ScALT2 codify proteins with 65% identity, which were proposed to be paralogous alanine tra...
متن کاملABA Biosynthetic and Catabolic Pathways
© Springer Science+Business Media Dordrecht 2014 D.-P. Zhang (ed.), Abscisic Acid: Metabolism, Transport and Signaling, DOI 10.1007/978-94-017-9424-4_2 Abstract Abscisic acid (ABA) is a phytohormone that regulates physiological processes such as seed maturation, seed dormancy, and stress adaptation. These physiological responses are triggered by the fluctuation of endogenous ABA levels in accor...
متن کاملEvolutionary Systems Biology of Amino Acid Biosynthetic Cost in Yeast
Every protein has a biosynthetic cost to the cell based on the synthesis of its constituent amino acids. In order to optimise growth and reproduction, natural selection is expected, where possible, to favour the use of proteins whose constituents are cheaper to produce, as reduced biosynthetic cost may confer a fitness advantage to the organism. Quantifying the cost of amino acid biosynthesis p...
متن کاملTechnological Specialization and Corporate Diversification∗
We document a trend towards fewer and more-focused conglomerates, and develop a model that explains these patterns based on increasing technological specialization. In the model, diversification adds value by allowing efficient within-firm resource reallocation. However, synergies decrease with technological specialization, leading to fewer diversified firms over time. Also, the optimal level o...
متن کاملSports Specialization vs Diversification
O ver the past 40 years or so, there has been a significant change in the direction of amateur sports in the United States. Way back when, participating in several sports (baseball, basketball, football, or track) was the goal of many high school athletes. If you could letter in 3, especially before your senior year in high school, that was quite impressive. Those who achieved this goal in thei...
