Genomic analysis of Rickettsia japonica strain YHT.

abstract：:Catabolism of nonphenolic arenes is frequently initiated by dioxygenases, yielding single isomer products with two adjacent hydroxylated asymmetric centers. The next enzymic reaction dehydrogenates these cyclic cis-diols, with aromatization yielding catechols for ring cleavage. There are two stereochemical questions t...
