| 1.1.1.21 | gene ALDRXV4, cDNA expression of His-tagged enzyme in Escherichia coli strain BL21(DE3) using pET28a expression vector. Overexpression of enzyme ALDRXV4 improves growth and tolerance against diverse abiotic stresses induced by high salt (500 mM NaCl), osmoticum (10% PEG 6000), heavy metal (20 mM CdCl2), and methylglyoxal (5 mM) in Escherichia coli cells.
