| Abstract: | Nucleotide sequence of Ralstonia metallidurans CH34 genome has been mined with respect to the genes probably involved in degradation of phenol or toluene by means of bioinformatics. Homology analysis of gene sequence and their deduced amino acid sequence revealed that a large gene operon including all structure, regulatory and facilitator genes required for degradation of phenol or toluene via meta-cleavage pathway was most likely present in the genome of Ralstonia metalliduransCH34. A positive cascade regulatory mechanism probably existed in R. metallidurans CH34. The results reported here offered a base for fully understanding the molecular mechanism of degradation of phenol or toluene by R. metallidurans CH34. |
