Applications of BBa_M50005

BBa_M50005 contains the alkG protein (ABO_2708) originating in the bacterium Alcanivorax borkumensis. It is meant to be used in conjunction with BBa_M50004 (alkB1 protein, ABO_2707) and other enzymes from A. borkumensis to degrade alkanes measuring up to 32 carbons as part of A. borkumensis' digestive process.

Stanford BioE44 "Team WERK" 12.10.2016
We transformed E. coli with both BBa_M50004 and BBa_M50005 in an attempt to replicate the first step of A. borkumensis' alkane degradation in different bacteria. Under proper induction (rhamnose), our Western blot protocol revealed high levels of alkG production. However, pH testing failed to confirm the cooperative function of alkB1 and alkG, with transformed bacteria in alkane-rich conditions behaving relatively indistinguishably from those in standard conditions. This may have been due to a failure in double transformation, with the two proteins being expressed at disproportionate levels.

This image shows the results of our Western Blot protocol (using an anti-His antibody). Low levels of alkB1 expression from singly-transformed bacteria are visible in the highlighted region; however, doubly-transformed bacteria expressed hardly any alkB1 production.

This graph shows the results of our pH testing; each dataset represents a different instance of transformed E. coli. Measurements were normalized against the initial pH of each bacteria culture. Under proper collaborative function of the alkG and alkB1 enzymes, pH ought to have decreased over time relative to the control; however, no concrete results were observed.
