WebOct 8, 2015 · From the proteins involved in chitin biosynthesis, glucosamine-6-phosphate N-acetyltransferase was only found in treated P. polonicum (Table 1). The gene coding for this protein, as well as the gene encoding an α-1,3-glucan synthase, is upregulated in A. niger treated with sublethal doses of caspofungin (Meyer et al. 2007). WebOct 1, 2024 · In a previous study, we used TAP-MS to identify Kkv-interacting proteins required for chitin biosynthesis. Accordingly, Fabp was identified as a candidate, which is a well conserved protein in different insect species (Esteves and Ehrlich, 2006; Zhu et al., 2024).As there are three different splicing variants for Fabp in Drosophila, we used RT …
