Chitin synthase enzymes
WebDec 15, 2024 · The cuticular chitin synthase (CHS-1) is the key enzyme in the biosynthetic pathway and arthropods are therefore especially dependent on its proper function. The present AOP describes the effects of CHS-1 chemical inhibition on the molting process leading to increased mortality in arthropods. Knowledge gaps still exist in the process … WebThe three chitin synthases of Saccharomyces cerevisiae, Chs1, Chs2, and Chs3, participate in septum and cell wall formation of vegetative cells and in wall morphogenesis of conjugating cells and spores. Because of the differences in the nature and in the time of execution of their functions, the synthases must be specifically and individually regulated.
