摘要:Aromatic oxygenases, which can catalyze the hydroxylation of aromatic
ring, have been widely used in bioremediation and chemical synthesis. In
this paper, the classification and application area of aromatic
oxygenases are summarized. Moreover, their discovery strategies based on
pure culture technology and metagenomic technology are discussed in
detail and first evaluated. Abundant of aromatic oxygenases have been
obtained using pure culture technology, but these enzymes exhibit with
single type, high repetition rate and low novelty. Emerging metagenomic
technology provides new ideas for discovering microbial resource from
uncultured microbes. However, it is still in the initial stage of
exploiting aromatic oxygenases by metagenomic methods, and many problems
such as low screening efficiency and hard to express heterologously have
not been resolved. This review evaluates the two strategies by analyzing
the content of genetic information, screening throughout and efficiency,
the time consume, cost, and expression feasibility of aromatic
oxygenase. And the metagenomic methods suitable for screening different
types of aromatic oxygenases are proposed. In the future, pure culture
and metagenomic technology combined with other omics technologies, will
contribute to promoting the theoretical study of aromatic oxygenases and
rapid development of biocatalysis industry. Fig 3, Tab 2, Ref 47
