Cloned (Comment) Organism
gene rv3229c, DNA and amino acid sequence determination and analysis, expression of wild-type and mutant enzymes in Escherichia coli as c-Myc and/or His-tagged protein, DesA3 expressed as a fusion with either a C-terminal His6 or c-myc tag has consistently higher activity and stability than native DesA3 having the native C-terminal sequence of LAA. The native C-terminal sequence of LAA apparently serves as a binding determinant for a mycobacterial protease/degradation system directed at DesA3. Fusion of only the last 12 residues of native DesA3 to the C-terminal of GFP is sufficient to make GFP unstable Mycobacterium tuberculosis
