Figure 3From: Detrimental effect of the 6 His C-terminal tag on YedY enzymatic activity and influence of the TAT signal sequence on YedY synthesisConstructs of the different YedY enzymes expressed in this study. The enclosed numbers refer to the proteins studied in this work: (1) corresponds to the C-ter tagged protein (31.4 kDa); (2) is the N-ter tagged enzyme lacking the signal sequence (-SS; 32.6 kDa); (3) is the N-ter tagged protein with the signal sequence (+SS; 32.6 kDa); and (4) is the untagged protein (30.4 kDa). The “V” symbol indicates the position of the TEV protease recognition sequence for cleavage.Back to article page
