Post-translational processing, metabolic stability and catalytic efficiency of oat arginine decarboxylase expressed in Trypanosoma cruzi epimastigotes

Nitric oxide synthase: A potential factor in loss of hydatid protoscoleces viability via its role in cholesterol immunomodulation

“…Several previous studies explained the different mechanisms of antimicrobial activity of iNOS [38,39] . In an in vitro study conducted by Zeghir-Bouteldja et al [40] , reactive nitrogen species were found to have a protoscolecidal effect, in addition to inducing In conclusion, the presence of cholesterol crystals in hydatid cyst fluid has not yet been sufficiently explained.…”

Translational and post-translational regulation of polyamine metabolic enzymes in plants

“…Studies in different organisms such as plants, yeast, and protozoan have shown that the activity of ADC enzyme requires a posttranslational proteolytic cleavage (Fig. 4) of an enzyme precursor (Bell and Malmberg, 1990;Hanfrey et al, 2001;Malmberg and Cellino, 1994;Serra et al, 2009). In oat plants, active ADC enzymes result from the proteolytic cleavage of a 66 kDa ADC polypeptide precursor into two polypeptide chains of 42 and 24 kDa (Malmberg and Cellino, 1994).…”
