expressed in Escherichia coli strain BL21(DE3)pLysS | Pseudomonas putida |
Protein expression in Escherichia coli strain JM109. Single colonies are picked and the DNA is isolated and screened for the desired mutation either by restriction analysis (C103A and C249A) or by sequencing (C140A and C220A). The overall fidelity of the PCR amplification and the presence of the desired mutations are confirmed by sequencing. The plasmids containing the mutated genes are then transformed into Escherichia coli strain BL21(DE3)pLysS for protein expression. | Pseudomonas putida |

additional information | - |
Good activity with several alternate substrates including the aromatic substrates, 4-chloro- and 3-hydroxy-benzaldehyde, as well as cyclohexanal. BADH is most active with medium chain aliphatic substrates such as pentanal and hexanal.The level of activity with aliphatic substrates drops off rapidly as the chain length decreased with very little activity (<0.1%) being observed with acetaldehyde. | Pseudomonas putida |
Storage Stability | Organism |
---|---|
Addition of 2 mM DTT to both stacking and resolving gels results in a decrease in the protein laddering effect, and both BADH and BADH-His are present as near-homogeneous species. | Pseudomonas putida |

The pH profiles are bell-shaped indicating that two ionizable groups are involved in the catalytic mechanism. | Pseudomonas putida |
5 | 10 | KM value for NAD+ increases from 0.3 to 1 mM as the pH changes from pH 5 to 10. The pH profile data are obtained at a NAD+ concentration of 5 mM, essentially saturating across the entire pH range. Similarly, data for the NADP+ pH profile are obtained at 10 mM NADP+ | Pseudomonas putida |
