TAG lipase activity of recombinant fusion proteins MBP-LipF and MBP-LipS
Lipase activity was measured by iodine-stained TLC and a NEFA-C assay. Values are means ± se for n = 3. Means identified by different superscripts are significantly different at the 5% level based on Duncan's multiple range test. Percentages relative to the pMal-c2 control are indicated. MBP, Maltose binding protein control produced from the empty pMal-c2 vector; MBP-lipF, full-length lipase fused to MBP; MBP-lipS, truncated lipase (lacking predicted transit peptide) fused to MBP.
