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.
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.
