In the present study, we attempted to control the pH profile of the catalytic activity of the industrially relevant alkaline protease KP-43, by incorporating 3-nitro-l-tyrosine and 3-chloro-l-tyrosine at and near the catalytic site.Thirty KP-43 variants containing these non-natural amino acids at the specific positions were synthesized in Escherich
In this study, the effects of melatonin-induced enhancement on the principal photosynthetic parameters and antioxidant machinery were investigated in Avena sativa (oat) plants exposed to polyethylene glycol (PEG)-induced osmotic stress.The parameters of growth, chlorophyll content, stomatal conductance, proline accumulation, lipid peroxidation, and
