ALDH generator (low expression)
ALDH is an aldehyde deyhydrogenase that facilitates the third step in alkane degradation, from n-alkanals to n-alkanoic acids (see figure 1), which can then be further degraded through β-oxidation
The [http://2010.igem.org/Team:TU_Delft#page=Project/alkane-degradation characterization of BBa_K398029] has been described on the TU Delft iGEM Team 2010 wiki.
Usage and Biology
Aldehyde dehydrogenase from the thermophile Geobacillus thermoleovorans B23. It functions as an octamer, requiring NAD+ as coenzyme. The optimum condition for activity lies at temperatures between 50 and 55 degrees celsius and and a pH of 10. You can see our original plasmid map below.
Characterization
This part was characterized at 37º C and pH=9.5, using recombinant strains carrying this part on the plasmid pSB1A2 by TU Delft 2010 iGEM team.
Results
[http://2010.igem.org/Team:TU_Delft#page=Project/alkane-degradation/results TU Delft 2010 results] suggest that the cell extracts obtained from the recombinant strain E. coli 029A, which expresses this part, have a dodecanal dehydrogenase activity twice as high as the control strain (E. coli with the empty plasmid pSB1A2). This activity is equivalent to 33.98% of the cell extract of Pseudomonas putida growing on octane as sole carbon source.
