Fig. 4From: Constitutive expression of active microbial transglutaminase in Escherichia coli and comparative characterization to a known variantEffect of organic solvents on the activity of mTG; WT (a) and S2P (b). The standard hydroxamate activity assay was performed with the addition of varying concentrations of organic solvents. 100% activity was defined as the activity in 50Â mM sodium phosphate buffer pHÂ 8. Results represent an average of triplicatesBack to article page
