Abstract:
Recent finding that a prokaryote synthesizes lysine through the alpha-aminoadipate pathway demonstrates that the lysine synthesis through the alpha-aminoadipate pathway is not typical of fungi. However, the fungal lysine biosynthesis is not completely the same as the prokaryotic one. We point out that alpha-aminoadipate reductase is a key enzyme to the evolution of fungal lysine synthesis. In addition, fungi have two different saccharopine dehydrogenases, which is also characteristic of fungi.
