“…These variations are typical microenvironmental changes in the tryptophan side chains that appear to be essential for enzyme activity. These data are in agreement with those reported for the GH10 endoxylanase from Penicillium chrysogenum 44 , in which the emission bands from pH 5.0 to pH 6.0 remained centered at 337 nm and shifted to 335 nm at pH 9.0, suggesting slight protein conformational changes.…”

“…It is known that tannic acid has a strong inhibitory effect on commercial cellulases 42 , with inhibition of up to 80% on the studied fungal cellulases and β-glucosidase 43 . Recently, Ullah and collaborators 44 reported a 17% inhibitory effect of tannic acid on GH10 xylanase from Penicillium chrysogenum using oat spelt xylan as a substrate. In contrast, Monclaro and collaborators 33 found a 12% increase in the activity of GH11 xylanase from Aspergillus tamarii in the presence of tannic acid using birchwood xylan as a substrate.…”

“…At the same time, several environmental damages are caused by the consumption of fossil fuels and the increase of greenhouse gases in the atmosphere, which drive the need for less polluting energy sources with better cost/benefit ratio, in addition to reducing the emission of harmful gases (Ullah et al al. 2019).…”

“…Como pode ser observado, e conforme era esperado para uma xilanase GH10, a Af-XYLA exibe uma estrutura de barril TIM clássico [(β/α)8], que consiste em 8 α-hélices (destacadas em rosa) e 8 folhas β (destacadas em lilás) ao redor de um sítio ativo de sulco profundo. Tal estrutura é condizente com a atividade endo-hidrolítica desta enzima (LIEW et al, 2019;ULLAH et al, 2019;SEGATO et al, 2014). Foram identificados 6 resíduos de cisteína (em verde) aptos a formarem pontes dissulfeto (destacadas em amarelo).…”
