Do you know the Transcription factor name for lapF and naphthalene dioxygenase?
pickupchik [31]

Answer:

The LapF gene encodes one of the largest proteins from Pseudomonas putida, it is required for the bacterial colonization on the solid surfaces; while naphthalene dioxygenase is an enzyme required for the process of aerobic degradation of naphthalene.

Explanation:

LapF is a gene of Pseudomonas putida that is critical during the process of plant root colonization. Mutations in this gene have shown to reduce the ability to colonize plant tissues. On the other hand, the naphthalene dioxygenase gene is also encoded by the genome of Pseudomonas strains. The naphthalene dioxygenase protein catalyzes the hydroxylation of different substrates, however, this enzyme is widely known for acting during the degradation of naphthalene, an organic chemical compound that is toxic in humans.
