Part:BBa_K398029

ALDH generator (low expression)

ALDH, an aldehyde deyhydrogenase that facilitates the third step in alkane degradation, from n-alkanals to n-alkanoic acids, 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. This part also works fine at 37º C.

This part was characterized in the plasmid pSB1A2. You can see our original plasmid map below.
