Genetic structures of the genes encoding 2,3-dihydroxybiphenyl 1,2-dioxygenase and 2-hydroxy-6-oxo-6-phenylhexa-2,4-dienoic acid hydrolase from biphenyl- and 4-chlorobiphenyl-degrading Pseudomonas sp. strain DJ-12
Article Abstract:
The pcbC and pcbD genes of Pseudomonas sp. strain DJ-12 encoding 2,3-dihydroxybiphenyl 1,2-dioxygenase and 2-hydroxy-6-oxo-6-phenylhexa-2,4-dienoic acid hydrolase, respectively, are present as an operon. The pCU103 plasmid contains an open reading frame (ORF) at position 82 which is the pcbD gene with 849 bp and another ORF of 960 bp from position 1022 is the pcbC gene. A promoter-like sequence is located upstream of the pcbD gene and ribosome-binding sites are present upstream of the initiation codons of pcbC and pcbD genes.

cumA, a gene encoding a multicopper oxidase, is involved in Mn(super 2+) oxidation in Pseudomonas putida GB-1
Article Abstract:
A study was conducted to investigate the mechanism involved in Mn2+ oxidation of Pseudomonas putida strain GB-1. Nucleotide sequence analysis of the transposon insertion site showed that a gene encoding a protein similar to multicopper oxidases is involved in Mn2+ oxidation. This gene was labeled a cumA. It was also found that GB-1 strain and other Mn2+-oxidizing speodomonads need Cu2+-binding proteins to facilitate Mn2+ oxidation in Pseudomonas putida.
