Cellular production processes using malonyl-CoA
In cellular metabolism, acetyl-CoA is the normal substrate for acetyl-CoA carboxylase. However, in approx. 10% of the reactions, acetyl-CoA carboxylase erroneously uses another substrate, butyryl-CoA, resulting in the formation of potentially toxic ethylmalonyl-CoA (figure). There is a need for removing this metabolite from cellular processes.
The UCL/WELBIO invention
The laboratory of Prof. Emile Van Schaftingen, WELBIO investigator at Université catholique de Louvain (UCL)– de Duve Institute, discovered and cloned ethylmalonyl-CoA decarboxylase (ECHDC1).
This enzyme decarboxylates ethylmalonyl-CoA to butyryl-CoA (figure) and methylmalonyl-CoA to propionyl-CoA.
Ethylmalonyl-CoA decarboxylase (ECHDC1) is described in mammals, but was not identified in bacteria or yeast.
Application
This material can be used in bacteria or yeast to improve cellular processes using malonyl-CoA (e.g. engineered fatty acid or polyketide synthesis) by preventing the formation of ethyl- or methyl-branches.
