Arrangement and regulation of the genes for meta-pathway enzymes required for degradation of phenol in Comamonas testosteroni TA441
Article Abstract:
Research has been conducted on the Comamonas testosteroni which degrades phenol. Results indicate that gene cluster aphCEFGHJI is downstream of the aphK operon.

Pseudomonas putida DE2010 can degrade biphenyl by a mosaic pathway encoded by the tod operon and cmtE, which are identical to those of P. putida F1 except for a single base difference in the operator-promoter region of the cmt operon
Article Abstract:
Pseudomonas putida DE2010 has been found to be able to degrade biphenyl by a mosaic pathway encoded by the tod operon and cmtE. They are identical to those of P. putida F1 except for one base different in the operator-promoter region of the cmt operon. Results of study show that cmtE is not effectively repressed by CymR in strain CE2010, leading to low constitutive expression and, as a result, low growth on biphenyl

Adaptationof Comamonas testosteroni TA441 to utilize phenol: Organization and regulation of the genes involved in phenol degradation
Article Abstract:
Comamonas testosteroni TA441 was able to utilize phenol following a 2-3 week incubation in a phenol containing medium. Phenol hydroxylase (PH) and catechol 2,3-dioxygenase (C230) were highly induced by phenol and an adapted strain P1, indicating that phenol was degraded through the meta-pathway. An aphR mutant strain of P1 could be grown on phenol after transformation with a recombinant aphR gene, although TA441 could not.
