Abstract: |
Ketosynthases are essential for several metabolic pathways and play a vital function in biosynthesis of carbon-carbon bond. Until now, decarboxylative Claisen reaction has been intensitively studied, while the research of ketosynthases which catalyzed the non-decarboxylative Claisen condensations is relatively scarce. Recently, some new progresses have been made in this field. In this paper, novel ketosynthases have been discussed including their enzymatic characteristics, structure basis, catalytic mechanism and application prospect. |
Key words: non-decarboxylative Claisen condensation ketosynthase |
