WebFeb 9, 2012 · The chitin synthase activity also was reduced in the chs6 mutant but the reduction was less than 2-fold. In contrast, the chs2 and chs5 mutants had higher chitin synthase activity than the wild-type strain . Nevertheless, their increase in chitin synthase activity was less than 2-fold in comparison with the wild type. WebChitin formation can be divided into three distinct steps. In the first step, the enzymes' catalytic domain facing the cytoplasmic site forms the polymer. The second step involves …
