2.7.8.7 | gene pptT, recombinant expression of His-tagged wild-type full-length PptT and N- and C-terminally truncated mutant enzymes in Escherichia coli strain BL21(DE3), the wild-type full-lebgth enzyme forms aggregates, expression of the enzyme with a ubiquitin-related modifier tag (SUMO) has no effect on the protein solubility, while fusion with the maltose-binding-protein results in a soluble fusion protein that can be purified | Mycobacterium tuberculosis |

2.7.8.7 | additional information | improved solubility of the full-length PptT compared to its N- and C-terminally truncated counterparts. In vivo, the highest fluorescence levels is attained for the full-length enzyme and N-terminally truncated variants whereas truncation of the last C-terminal residue L227 is sufficient to negatively impact the fluorescence intensity of the colonies | Mycobacterium tuberculosis |
